“Set better boundaries” has become one of the most repeated pieces of advice in conversations about mental health. It’s also one of the least actionable, because the people who most need to hear it are usually the ones for whom boundaries feel nearly impossible.
If you’ve ever said yes when you meant no, stayed in a situation long past the point it stopped working, or felt responsible for everyone else’s feelings except your own, this is worth understanding more deeply than a list of scripts to memorise.
What boundaries actually are
Boundaries are not walls. They’re not about shutting people out or becoming cold or difficult. A boundary is simply clarity about what you will and won’t accept: in how you’re treated, how your time is used, and what you’re responsible for.
The confusion often comes from conflating boundaries with ultimatums. An ultimatum is aimed at controlling someone else’s behaviour. A boundary is about your own. “You have to stop doing that” is an ultimatum. “If that continues, I’ll need to step back from this situation” is a boundary.
Why they’re genuinely difficult for many people
For people who grew up in environments where their needs were consistently deprioritised, setting boundaries can feel, physically and emotionally, like doing something wrong.
If expressing needs was met with anger, withdrawal, or criticism in childhood, the nervous system learns that having needs is dangerous. Saying no starts to feel like a threat to the relationship, or a confirmation of some feared belief: that you’re too demanding, that you’ll drive people away, that your needs don’t really count.
This is where boundaries go beyond a communication skill. For many people, the difficulty isn’t knowing what to say. It’s tolerating the anxiety that comes with saying it.
Common patterns that signal boundary difficulties
- Feeling responsible for other people’s emotional states
- Chronic people-pleasing, even with people you don’t particularly like
- Resentment that builds quietly because needs go unspoken
- Saying yes and then feeling trapped, angry, or depleted
- Difficulty distinguishing between your feelings and someone else’s
- Feeling guilty immediately after asserting a need
What doesn’t work
Scripts and phrases alone rarely solve this. You can memorise “I’m not available for that” and still be completely unable to say it when the moment arrives, because the issue isn’t vocabulary. It’s the underlying discomfort with disappointing people.
Equally, framing boundaries as purely selfish self-care sidesteps the relational reality: clear boundaries actually improve relationships. People who know where you stand can trust what you say. Resentment decreases. Interactions become more genuine rather than more guarded.
How to start
Start with low-stakes situations. The first boundary doesn’t have to be the hardest conversation you’ve ever had. Declining a commitment you don’t have the energy for, or asking for more time before making a decision, builds the muscle gradually.
Notice the discomfort without acting on it immediately. The guilt or anxiety that follows setting a boundary is real but usually temporary. Sitting with it, rather than immediately backtracking, is how tolerance builds.
Separate your feelings from your responsibilities. Someone being disappointed by your boundary is their feeling to manage. Feeling sad that they’re disappointed is yours. These are different things.
Work on what’s underneath. If boundaries feel impossible rather than just uncomfortable, that’s worth exploring more deeply. The difficulty usually points to something specific: about early relationships, about how love and compliance became entangled, about what you learned about your own worth.
Mental Health Counselling offers a space to explore exactly this, not just what to say, but why it’s so hard to say it, and how to build the internal capacity to hold your own needs alongside care for others.
Boundaries aren’t about caring less. They’re about being honest about what you can genuinely offer, and that honesty, in the long run, serves everyone better.
