Back in 2000 and 2001, I was in severe depression much of the time. I was also dealing with symptoms of PTSD, including anger and anxiety.
The psychiatric medications weren't working for me. Hence, the psychiatrists recommended ECT treatments for me.
Unfortunately, the ECT treatments didn't work for me. It didn't help me emotionally. Also, I don't remember much about my life during late 2000 and early 2001 because of the ECT treatments.
However, the ECT treatments were not a thing of last resort for me, as a few months later, I was put on meds that actually helped me a lot emotionally.
