Oh definitely, I was suicidal from the age of around 8 or 9, most of my decisions in life have revolved around the fact that I'm going to ctb. I used to have crippling anxiety about everything, but after my first attempt I stopped caring.
It's a double edged sword. On one hand it has made life a lot more easier, I don't worry about the mundane things, I take more opportunities which makes life a lot more exciting. On the other hand it has caused me to do a lot of stupid shit, I do a lot of risky behaviour because I have no care if I live or die, this has caused me to get SA'd, abused, and other traumatic things.
It does make some things easier, but the trauma it causes outweighs any positives. But it's irreversible, I've lived like this for too long, my SI is practically non existent now. The only way to avoid getting abused again is to shut myself in at home, but I can't live like that for too long it's just too lonely.
