I've (18m) recently gotten myself into a job that I hate. Like, hate. It's a package handling company that was hiring for overnight “package sorters” and o just can't do it. It's too physically demanding and most of my shifts start at 3am. I desperately need to quit, because my mental health is absolutely tanking and idk how much more pressure I can take. I want to quit over the phone, as going into my 3am shift just to quit is stupid. How should I go about it? I'm autistic and scared shitless that I'm gonna come across as mean and flakey.
