My situation looks quite a bit like yours, though for entirely different reasons. I too rarely go out of my house and to an outside observer it probably appears that I have no friends. What I have found over the years is that most people don't want the type of friendship that I am interested in having. I am not looking for companionship or someone to 'hang out' with in a friend; I'm looking for someone that I can call at three o' clock in the morning, say 'I need you now' and they ask no questions and are at my door in 10 minutes. Those people are few and far between.
