Depressed..

I battle severe depression & anxiety. Along with Bi Polar. I have been on some medication as a teen, but have yet to find a medicine that works. Most days I struggle to live. I find myself crying almost every day because I feel as if I will never escape this mental hell & i dont know what to do anymore. I want to throw in the towel. I wish so bad to have a "normal" mind. I need some help..
