Cured is a very strong word (at least for me).
However I think I have mostly beaten my melancholy and depression through a mix of therapy (brainspotting, which is an offshoot of EMDR) and low dose lithium aspartate (5mg twice a day). Much of my depression was due to repressing traumas, which the brainspotting therapy helped me face and put behind me.

I try not to take anymore supplements or medications than I need, and when I've tried to stop the lithium aspartate the depression came back and I went back on.
Lithium is (as far as I know) also the most effective anti-suicide medicine out there.

My anxiety is a different story. Ugh. I can handle the day to day anxiety, but the panic attacks I get occasionally can last for hours or the whole day. Hell on earth.
