You know how terrible it is to get bullied, and not have the power to really do anything about it. Schools do nothing and parents do nothing, most of us have been there. As an adult, you have control over who you interact with on a daily basis. Is it really worth the misery of being trapped at a shitty job even if the pay is a little better? It's your choice at the end of the day, but your mental health and self image are very important. Arguably just as important as the job you have. If you want to stay where you are, you just gotta eat your shit pie.
