I really feel like i need to self harm.

Been going through a lot of stress due to work and shit. I really feel like doing it even if im 2 months sober, honestly i dont care about that. The thing is i cant do it cuz ill get fired if my boss sees it. I work at a fast food restaurant and our uniforms are short sleeved, we are NOT allowed to use long sleeved shirts.

I really dont know what to do.
