One of the most important skills Mind Health clinicians work on with clients is also one of the hardest: boundary-setting. And the hardest part is usually not the boundary itself — it’s the guilt that arrives the moment you set it.

A client recently told her psychologist, “I said no to my boss about working weekends, and I felt like the worst person alive.” She’d had a legitimate need, communicated it clearly, and the guilt that followed was disproportionate to anything she’d actually done wrong. That guilt is what stops most people from setting boundaries at all.

Across two decades of clinical work, I have seen the same pattern: boundary problems aren’t about being selfish or mean. They’re about confusion — confusion about what boundaries actually are, where they come from, and why we feel so terrible when we set them.

What Boundaries Actually Are (And Aren’t)

A boundary is not a wall. It’s not rejection. It’s not saying “I don’t care about you.” A boundary is a clear statement of what you will and won’t do, and it exists to protect your wellbeing and create space for authentic relationships.

Think of physical boundaries first, because they’re easier to understand. If someone keeps standing too close to you, invading your physical space, you step back. That’s not mean — you’re just maintaining the distance you need to feel comfortable. A boundary is the same thing, but applied to emotions, time, energy, and information.

Some examples of what boundaries actually are:

  • “I love you, and I can’t lend you money right now.”
  • “I’m not available to talk about this on the phone. Can we email instead?”
  • “I need to leave the conversation when yelling starts.”
  • “I’m not comfortable with that topic. Let’s talk about something else.”
  • “I can’t come to every family gathering, but I’ll make the important ones.”
  • “I’m switching off my work email after 6pm on weekdays.”

Notice what these aren’t: they’re not angry, they’re not rejecting the person, they’re not demands. They’re statements of what you need to take care of yourself.

The Root of Boundary Problems

Most people who struggle with boundaries learned early that boundaries weren’t safe. Perhaps a parent responded to “no” with punishment or withdrawal of love. Perhaps a parent was emotionally dependent on the child — and so the child became responsible for their feelings. Saying no meant they’d be hurt, and it would be your fault. Or perhaps you learned that your needs were less important than others’ needs, so you stopped having needs altogether.

I recently worked with a woman we’ll call Claire, who couldn’t say no to anyone. Clients would text her at midnight with work questions. Her family would drop by unannounced. Friends would vent to her for hours while she sat silent. Claire felt resentful and exhausted, but when her psychologist suggested she set a boundary, she said, “I can’t do that. What if they get mad at me?”

What Claire didn’t realise was that people were already getting angry at her — she was just experiencing it as her own fault. By setting boundaries, she was actually creating the conditions for clearer, more honest relationships.

Guilt vs. Responsibility

This is crucial: feeling guilty does not mean you’ve done something wrong. Guilt is just a feeling. It’s information. And when it comes to boundaries, guilt often tells you more about your history than about reality.

Here’s a concrete example. If you say no to lending money and feel guilty, ask yourself: “Have I actually wronged this person?” Usually the answer is no. They asked, you said no, and that’s the end of the story. The guilt you feel probably comes from an old message: “If someone I care about is struggling, I have to fix it, and if I don’t, I’m a bad person.”

That’s not true. You are not responsible for other adults’ happiness, financial security, or emotional state. You’re not selfish for having needs. You’re not mean for saying no.

There’s a distinction I come back to repeatedly: responsibility means you caused harm and need to repair it. Guilt is just a feeling that can exist independently of actual wrongdoing. A lot of boundary-setting is learning to sit with guilt while doing the right thing anyway.

Types of Boundaries

Types of Boundaries: Setting Boundaries A Psychologist’s Guide to Saying No Mind Health

Emotional Boundaries

These protect your emotional wellbeing. They’re about not absorbing other people’s emotions as your own. “I care about you, and I can’t be your therapist.” “I’m not responsible for managing your anger.” “I need to step away from this conversation before I lose my temper.”

Emotional boundaries are particularly hard for people who grew up in families where someone was emotionally dependent on them. But they’re essential. You cannot help anyone if you’re drained from absorbing their emotions — a dynamic I often see driving the slow burn toward burnout.

Physical Boundaries

These are about physical space and touch. For some people, this is about family members who hug when it’s not wanted, or partners who touch in ways that feel intrusive. “I prefer a handshake.” “I need some physical space right now.” “Please ask before you hug me.”

Time Boundaries

These protect your time and energy. “I can’t chat during work hours.” “I’m not available for phone calls after 8pm.” “I need one night a week that’s just for me.” “I can visit for two hours, but I need to leave by 5pm.”

Time boundaries are increasingly important in a world where people expect immediate responses to messages. Your time is finite. Protecting it is not selfish.

Digital Boundaries

In the modern world, these deserve their own category. “I’m not on WhatsApp.” “I don’t discuss personal matters via text.” “I mute notifications after work.” “I’m not available on social media.”

Digital boundaries let people know how to contact you and when you’re available. They prevent the expectation of constant connectivity — which, left unchecked, quietly feeds chronic stress.

Scripts for Common Situations

Often, people struggle with boundaries not because they don’t want them, but because they don’t know what to say. Here are scripts I often suggest:

A family member who visits unannounced: “I love you, and I need a bit of notice before you visit. Can you text before you come over?”

A friend who vents constantly: “I care about you, and I’ve noticed I’m the person you come to when you’re struggling. I think it would be good for you to talk to a counsellor about this, because I’m not equipped to help in the way you need.”

A boss who emails at weekends: “I’m not checking email outside of work hours to protect my wellbeing. I’ll respond to anything urgent when I’m back in the office Monday morning.”

A partner who brings up old conflicts: “I understand this hurt you, and I’m not willing to revisit it every time we disagree. If you want to work on this, let’s do it with a therapist.”

A family member asking for money: “I love you, and I’m not in a position to lend money right now. This is a firm boundary for me.”

Notice the pattern: you name the person or relationship, you state your boundary clearly, and you usually explain why (briefly). You don’t over-apologise or over-explain.

What Happens When You Set Boundaries

Here’s what usually occurs: the person reacts badly. They might accuse you of being cold, selfish, or ungrateful. They might cry. They might go silent. They might tell you that you’ve changed and not in a good way.

This is actually important information. What they’re communicating (usually without meaning to) is: “I liked the old arrangement where my needs came first.” They’re not wrong — that was the arrangement. You’re just ending it.

What Happens When You Set Boundaries

If someone reacts to your boundary by punishing you (withdrawal, guilt-tripping, anger), that’s information that the relationship itself might have problematic dynamics. That’s not an argument against boundaries; it’s an argument for them. You need to see what this relationship actually looks like without your self-sacrifice.

The relationships that matter will adapt. People who genuinely care about you will respect your boundaries once they understand you’re serious. It might take time and it might feel awkward, but they’ll adjust.

Boundaries Improve Relationships

This is counterintuitive, but it’s true: boundaries don’t damage relationships. They improve them. Here’s why:

When you have no boundaries, you’re likely to be resentful and burnt out. You say yes when you mean no, then you feel angry. You give until you’re empty, then you withdraw. The other person can feel the resentment, the distance, the fake compliance. The relationship becomes strained — a pattern explored in our piece on the poison of resentment.

Boundaries Improve Relationships

When you have clear boundaries, you can be genuinely present. You say yes when you mean it, so your yes has weight. You give from a place of choice, not obligation. You can actually relax with people because you’re not silently seething. The relationship becomes real.

The Gift of Boundaries

Setting boundaries is an act of self-respect. It’s saying, “My wellbeing matters. My needs count. I’m worthy of consideration.” And when you believe that — when you actually embody it — everything changes. Your relationships become real. Your energy recovers. You stop being small to make other people comfortable.

That’s the gift. And it’s one I wish for everyone who walks through our doors.

Frequently Asked Questions

Why is it so hard to set boundaries?

Boundary-setting challenges often stem from people-pleasing patterns, fear of conflict, and beliefs learned in childhood. Many confuse boundaries with selfishness, when they are essential for healthy relationships and stress management.

How do I set boundaries without feeling guilty?

Guilt is normal initially. Start small, use clear and kind language, and practise self-compassion. Over time, boundary-setting becomes more natural. A psychologist can help build these skills.

What are examples of healthy boundaries?

Saying no to extra work when at capacity, limiting time with draining people, not responding to messages after hours, and protecting your sleep routine.

Can a psychologist help me learn to set boundaries?

Absolutely. Psychology sessions help you understand why boundaries are difficult, develop assertiveness, and practise in a safe environment. Book an appointment to get started.
