First up, everyone is different. Some people can be alone for days without fuss, others feel like you.

I can easily do days without other people, but I would keep myself very busy (hobbies, sports, projects, books...).

If you are unused to it, avoid just passing time doing nothing or watching TV, find a purpose to your alone time.

If you can't, don't sweat it and find a roommate or a partner :)
