Aww, sorry to hear sweety. It doesn't sound like your meds are working. Head to the ER, tell them your suicidal and your psych meds aren't working, and get a committal to help pull you together. It also gets you out of the house. They have programs to hook you up with and places for you to go, they want to keep you safe.
I have to take a little bit of Prozac to pull me out of permanent depression when stabilized.
Good luck with that!
