Loneliness is something I'm going through now, but I have to say that I'm already doing a lot of these things on my own.
I went to the movies last night by myself, for example. EDIT: Actually, going to the movies and to a cafe and stuff on your own is pretty cool. You can take as little or as long as you like. Plus at both places you can stuff your face and there's nobody there to tell you off (although you may get some looks, haha).
