A few months ago I was yelled at by my boss. This wasn't due to me at all. He was having a bad day and took his anger out on me. It caused me to have an emotional breakdown. He apologized, but I'm still a bit bitter about it. I have anxiety issues and this has caused me some problem, but I decided to go on.
Yesterday I was talking to the same boss (the big boss passed away between when I got yelled at and now so he is completely in charge now). We talked about the previous incident and I said I was going to do my job. He told me that isn't doing my job and if I wasn't willing to do more then he would need to find someone else. I told him I'd think about it but I have anxiety issues right now about the situation. I was thinking about looking for another job, but I hate looking. I thought about just lying and say yes (I think my normal job is what he wants, but I don't know). I also thought about telling the truth that I won't do more work for him and getting unemployment when I get fired, then look for a job. He wants me to give a heads up before I quit, but I don't want to do that because I hate this boss (you might guess, but he is rude). We may talk about this again, but he may not follow up either.
I find that thinking things through and talking a bit should help my anxiety a bit a help me solidify a decision.
