As someone said on this website, there is impulsive suicidal ideation and there is prolonged suicidal ideation.
I've been suicidal for a long time as I find no reason to live, for me existence has no meaning so i might as well die and avoid all the suffering. I have no goals, no ambitions and no one to look up to. You shouldn't worry about me tho because I have no reason to kill myself so you can't talk me out of it, no reason means nothing to fix. Atleast I'm not killing myself out of an impulse. Most people who "get better" after an attempt or after being suicidal are those who have impulsive suicidal ideation. I don't think going to therapy or any other form of treatment would ever help me change my mind.
Also, why do people have a hard time accepting suicide?
