You know, you probably qualify for medicaid (since you are currently unemployed and have a child at home) and, while I know the state has crp for mental health specialists (they must get the drop outs or something), you could still get some anti-depressants. Which will be better than nothing at this point.
Tomorrow, bake a cake! Put candles on it! Sing happy birthday. Feast on cake and ice cream! Enjoy your special day being you!! ;)
sometimes, and again this sounds really hokey, a journal can help. There are a billion online places you can journal so you don't feel all alone. Just search for "blogging" or something. Myspace is a good way to 'meet' people to chat with - as are various other places.
Not that any of this fixes your problem, I understand - but it might make you feel less lonely for awhile.
