I hate my job and the bad treatment from the manager and owners so much I just want to walk out on them and leave them short staffed.

It is seriously affecting my mental health and I hate it. But there is not another job I feel like I can do with my social anxiety! And I don't have a college degree. I have been looking for other jobs though. I have been taking xanax nearly every day to deal with my anger, anxiety, boredom, and dread at work. I have not had negative symptoms on the days I don't take it but I am worried I could be headed in that direction. Please say something that may help me! I am losing my head. Not really but I am FED UP.
