If you're still around this is how I attempted to ctb a decade ago. picked out a nice spot at the lake, bought a hand gun from the flea market, sat there for a couple of hours and just could not do it. I don't know what went through my mind exactly. it was like others said, got the gun up to my head, had the trigger pulled almost far enough but I just couldn't do it. and yeah part of it was the "what if" it didn't work. I also remember how stupid my problems looked and how I wanted to give meds a shot, go to school, etc. a decade later and I'm still fucking crazy, even worse off financially, and still wanting to ctb so...
crazy thing was a few months after I got back from my grippy sock vacation my friend's mom actually pulled the trigger and it didn't work. she has to wear diapers, her ex-husband had to come back and take care of her like she's one of her kids. her grown kids had to watch her like she was a toddler for years. for a couple of months they thought she was going to be a vegetable. she's capable of doing basic tasks now but goddamn my next attempt is not gonna be with a gun.
