It can really help when you take the focus off yourself and just do something totally selfless and generous for someone else, despite how awful you feel. (It really works.) It seems the worse you feel initially, the better you end up feeling afterward! Maybe order dinner for some homeless people or spend the evening watching tv w/ an elderly person who is totally alone. Or buy a really nice toy for a little kid whose family doesn't have much money. I think it will make you feel a lot better!
