Is it normal to want to be left alone?
Yep.Totally normal
Yes. Wanting time to yourself is normal, whether you need a quiet moment to recharge or simply don’t feel like socializing.
People have different needs for company, and even very social people sometimes want everyone to give them a little breathing room. It can be a way to recharge, focus, or enjoy your own company—not a sign that you dislike everyone around you.
It’s worth noticing how it feels, though: peaceful alone time is different from feeling cut off or wishing you could connect but can’t. If being alone is making you unhappy, you can take it one small step at a time and let someone you trust know what’s going on.
