Is it normal to not like visitors?
Mostly.Normal for most people
Yes. Plenty of people find visitors tiring or prefer having their home to themselves; it doesn’t mean you dislike people.
Your home may feel like your place to recharge, so having someone over can feel like work: planning, hosting, making conversation, and giving up some privacy. Some people love spontaneous company; others would rather meet friends somewhere else or keep visits short. Both are normal preferences.
You can be kind and still set limits—like asking people to plan ahead, suggesting a café instead, or saying you’re not up for company today. If you want visitors but feel unable to see anyone because of intense fear or distress, that may be worth paying attention to; otherwise, you don’t have to become a host-at-heart.
