Im confused? What should I do?

I suffer from Severe OCD/GAD, depression, and maybe bipolar disorder. I've had these problems linked for years now, but during the past 2 years, my entire life has changed, because its gotten severe during that particular period of time. I've been to a psychiatric hospital, where I wasn't treated properly (told their was nothing wrong with me), I almost dropped out of school last year (used to be an honor student), I almost killed myself, self injured myself, self medicated back in January, and caused severe psychosis. Here I am still dealing pretty much with the same thing. I changed my life, and tried to face my fears, but I'm still being bombarded by them almost every moment. I've taken CBT therapy too, and I still have a lot of problems. I tried of living this way. I've kept being told Ill get better so many times, years ago, and here I am. I dont know, but I feel like I don't even want to take meds anymore, or go to a councilor, because I have been for a while, and im still dealing with pretty much the same thing.
