I think you’re expecting totally ridiculous things out of work.
This is your first real job and you don’t understand work boundaries. I think that is your issue with work in a nutshell. You think it’s like college or high school where you can do work but you also can flirt and joke around, and maybe you can at some jobs, but not this one. Nobody knows you, you’re markedly younger than everyone else in terms of stages of life, and you’re isolated and lonely. Look into counseling and find some other outlets. Join a gym, join community events, whatever it is that interests you. Make friends outside of work. Call your mom.
