About 25 years but it comes in waves. Sometimes want to CTB, others I get on with life.
Once someone is suicidal once in their life, its highly likely we will die to suicide, even if we seemingly recover and get well.
The last year or so has been a more towards wanting to CTB but the SI gets in the way every time.
Over the years I have done some crazy stuff, setup and built a guillotine, setup an intricate H2S system, tried CO in a tent, went to jump, setup hanging rigs, been in possession of cyanide, pentobarbital and SN. I do NOT have any of these substances or machines setup anymore - before the police want to smash down the door at 5am.
