Oh, I'm sorry if you've already mentioned the fact that you stopped asking folks to visit because they always make excuses. But I seem to recall other folks having this same issue, so you're not alone in that anyway. Still sucks though.
And I completely understand it being difficult going out to visit others. I mean, I don't know your full circumstances, but I know that even if I don't have a severe physical handicap, I still have several mental obstacles to go over before I go out...for instance, what to wear. Winter can be easier if I don't have to take my coat off, for I can pretty much just cover everything up and not care how it looks or if it even matches. Lol

But I guess I don't really have much to add in terms of advice, but I'll second the notion that you should question what you're feeling hopeless about. Maybe even share those with a therapist or trusted friend who might be able to help you overcome them.
