I have this « job » that I’ve been stuck with forever now.

How are you stuck?

Unless you're literally a slave (which I doubt), the only way one could be "stuck" in a job is because we live in a capitalist society where you need employment to survive. I had a miserable job a few months ago, to the point where suicidal thoughts I hadn't had in a while crept back up. I just quit. Even if that meant uncertainty with regards to housing/groceries (I still haven't found a job and not going to lie, shit's a bit rough right now).

If you're thinking of killing yourself anyway, why not quit? Why not drastically change your life? What have you got to lose? Surely not your will to live. Either you're going to be miserable (which it sounds like you're already there) or maybe things will eventually get better. Either way, you're not going to get much lower morale than being suicidal.

Best of luck to you, I hope you figure out a way to see yourself out of this. For what it's worth, this internet stranger believes in you. Hope to see you tomorrow.
