So I've been having a lot of panic attacks lately due to anxiety at work, so I've decided to quit and work freelance. The only thing is I don't know how to tell them. I know you're supposed to give 2 weeks notice but I don't think I can. I've used up my sick days, but I was too scared to say it was because of my anxiety attacks so I said I was having migraines. It's a call center job and I've only been working there 2 months, so I think I'm just going to call and leave a message. I'm trying to be polite, but I don't know what to say. Any advice?
