Is it normal to not want to be around people?
Depends.It depends
Yes, it’s normal to want plenty of time away from people; some people recharge best alone. If you’re avoiding everyone even though you feel lonely or it’s getting in the way of life, that’s worth paying attention to.
Lots of people would rather have a quiet night in than make small talk, and your appetite for company can change depending on stress, energy, and who you’re with. You don’t have to be a social butterfly to be okay.
The useful distinction is whether solitude feels restful or whether you feel trapped in it. If you want connection but fear, low mood, or overwhelm keeps you from people, or it’s disrupting things you care about, consider talking it through with someone you trust or a mental health professional.
