Is it normal to be comfortable alone?
Yep.Totally normal
Yes, it’s completely normal to feel comfortable on your own. Enjoying solitude doesn’t mean you dislike people or that anything is wrong with you.
Some people recharge by being around others; others genuinely enjoy their own company. You might like the quiet, freedom to do things at your own pace, or simply not feel a need to fill every moment with company. There’s no required amount of socializing that makes you normal.
The useful distinction is whether being alone feels chosen and satisfying, or whether you feel lonely and cut off when you don’t want to be. You can love your solo time and still care about people and enjoy seeing them.
