I don't think Tone303 is referring to "torture depression" as a medical term; of course it doesn't exist. I think Tone303 means a torturous, severe, intractable depression, which I can totally identify with, having suffered it for probably 40 years.
Dysthymia is a mild, yet chronic, depression. It does not apply here.
I do not qualify for any medical studies because of medical conditions. My insurance won't pay for one treatment. My doctor has almost run out of medications to try with me, and he is loath to try one that I suggested because he is scared.
I tried to kill myself two weeks ago, and I'm sorry it didn't work. I want a peaceful death, or obviously, I could kill myself any way.
I have a hellacious family, in addition. But if my mind could heal, they wouldn't bother me.
I don't know what I could have done to deserve this mental torture every second of every decade.
