Social exhaustion often comes from being a "people pleaser" — trying to satisfy everyone.
Psychological research shows that healthy relationships are built on "boundaries." Learning to say "no" isn't selfish — it's self-protection. Real friends won't leave because you set boundaries — if they do, the relationship wasn't healthy to begin with.
We often fear setting boundaries because we worry about being rejected or isolated. Ironically, it's precisely the lack of boundaries that leads to deeper exhaustion and eventual distance. When you constantly accommodate others, you're actually suppressing your authentic self.

Building boundaries doesn't happen overnight. Start small: decline an unnecessary gathering, postpone a non-urgent request, give yourself an afternoon of solitude. Gradually, you'll discover that those who truly care about you will respect your boundaries.
Remember: your time and energy are finite resources. Spend them on the people and things that truly matter.
