Is it normal to like being alone all the time?
Mostly.Normal for most people
Yes, it can be perfectly normal to prefer being alone, even most of the time. It’s worth paying attention if you feel lonely, distressed, or cut off from people you actually want in your life.
Some people recharge through company; others recharge by having the place to themselves. If you enjoy your own routines and don’t feel like you’re missing out, there’s nothing wrong with preferring plenty of solo time.
The useful distinction is whether being alone feels like a choice or like a trap. If you want connection but anxiety, low mood, or other worries keep you from getting it, that’s different from simply liking your own company—and it may help to talk it through with someone you trust.
