I'm very sorry you're feeling this way, michelle! Do you have a history of depression and anxiety, and if so, are you being treated for it?
No one should have to walk through life feeling overwhelmed and hopeless. You can always come here and talk to your friends on WH, vent, get it all out.
As for your boyfriend... why is it that you stay with the guy, when you can't get along, and don't even have sex? It seems like your boyfriend and this relationship might be contributing to why you're feeling so lonely and depressed. You deserve to be happy. You deserve to be with someone who helps make you happy.
