Has anyone else been dealing with a diagnosed mental illness, be it depression, anxiety, personality disorders, psychotic disorders, etc; that has not responded to any treatment?

I been suffering for over a a decade. Been diagnosed with several disorders over the years. Since the beginning, I been taking medications and was always in therapy, many different therapists over the years. Not only have I never got better or improved but I actually been getting worse steadily over the past 3 years. I don't have hope anymore, and I don't see the point in giving it time or having patience, as that is what I been doing for over 10 years. But the fact that it just keeps on getting worse and worse as time goes on is really extremely discouraging and makes me feel I am beyond hope and help.

If anyone else is dealing with this, how are you coping? How long have you been dealing with this? What have you tried?
