My SO is going to be mad when he gets home because I just quit my job today this was my last week but when I tried to put on my uniform it wouldn't fit I got so frustrated I have already asked my job for new uniforms but they said no . I work nights and my job is stressful and I'm exhausted. He wanted me to work until I start my new job Thursday but I need a break . I hope we don't get into a argument
