I've had that thought over the years, like what the f*ck have I done? I've destroyed everything, and I probably could have ridden it out, or rode through it.
But then a day comes along where the suicidal impulse or permeation just creeps into me unconciously like a poison, or I explode looking for a fight when someone is a complete social asshole, or passing out for days at a time on the couch after a stressful time.....
When I think that it's been happening for over 8 years, I cut myself some slack.
