The easy answer would be a combo of an aggressive ECT treatment regime and a psych meds cocktail of last resort. There could have been other contributing factors I just don't actually know.

You have to understand, that I had "checked out" as a member of the human race. I have this vision of me sitting in the psych ward that plays over and over.

I see myself sitting there, tears streaming down my checks but no other signs of life. I just sit there, not moving, not talking, just sitting staring into nothingness. Then the techs come and lead me away. The vision ends in silence, complete silence.

The ECT treatments were particularly aggressive because I wasn't responding to treatment. When or at what point everything became nothing, I don't know.
