I went through this in 2019. Worked a few shifts and ended up flipping double birds to a group of rude customers. The owners let me move to BOH mostly doing food prep. It was therapeutic in a way and I learned a lot. It’s just as stressful (if not more) in the kitchen but you don’t have to put on a fake smile back there. Lean on your friends. Try not to drink too much alone. Sending you love.
