So I work at a retail store and I want to quit without a notice but I'm terrified. It's my first job and I have a lot going on in my life right now and my doctor recommends I quit as soon as possible. I get treated poorly there so nobody understands why I'm having such a hard time just giving them a letter or call saying I won't be coming in anymore. Does anyone have any good advice? I'm just too scared to tell my manager.
