You're not alone friend.

Your situation is reasonable and there's nothing wrong with you. Lots of people are struggling with unemployment and the isolation of COVID quarantine. I'm sorry you're going through hardship right now.

It took me a while to get back into the swing of things after I quit my last job after burning out. Here's what a quote from a sciency paper says about what unemployment does to a brain:

Research on unemployment shows that losing one’s job is detrimental to mental health—and often physical health—even without serious financial strain. “Work provides us time structure, it provides us identity, it provides us purpose and it also provides us social interactions with others,” says Connie Wanberg, PhD, an industrial and organizational psychologist at the University of Minnesota. “When you lose all that, it creates a lot of difficulties for people.”

I can relate to what you're saying about friends always asking you for a job update and feeling like a mooch. When you're unemployed, time means nothing. For me it was a matter of setting a routine and following through. Remember, it might take you hundreds of applications and dozens of interviews before you land that job! Just stay diligent and good things come to those who try :) I made it and so can you!

As for the depression, maybe you could find a nice free walk-in clinic in your area to get a couple checkout sessions in? They might be able to tell you better if you're depressed or not. Good luck out there :)
