Have you ever overcome depression?

i've been depressed for 15 years since I was ten. I've seen therapist, psychiatrist, counselors, hotlines the works, took the antidepressant, joined the gym, met new people, went out into the world went to school, got a job, traveled, prayed, I even understand that depression is in fact pointless. I know that my life is my cirstances combined with what beliefs i give value to or not but- none of it worked. Im especially more miserable now then ever as days p and I learn more and more how random and twisted reality can be for everyone no matter who they are or what they practice. Please, anyone who has any other suggestions for curing depression, enlighten me.
