"I agree with everything you have said. I know my downfall was initiated by a series of horrible stressors some of which there was no logical way out for me. And others, there was a way out but not quickly, by no means quickly."
PTSD is a result of a severe stressor plus the feeling of inevitability or being trapped whether physically (think soldiers in war under attack) or psychologically like you describe.
I second your advice about not getting too attached to a treatment option as well as trusting yourself to figure some of this out since it seems a lot of this is not fully understood yet.
