Scheduled for 9 days in a row

on accident, for the second time in a month. I told my supervisors I need a day off once every 5 shifts and they need to find me a replacement for tomorrow. They couldn't do that for tomorrow so I'm going to work a 6th day. "why don't you just try again on the 7th day" because im off thursday and friday, so then most of this coming week I would be off. My next pay period begins monday!!! So am I wrong if I call in sick tomorrow? I called in sick 3 times in september because i got really sick. Am I wrong? I don't want to work 9 days in a row... AGAIN!! Everyone else at my work gets to have a day off every 5 days but because im closer its different for me. So unfair. I deservve to take care of MY mental health. So I don't feel bad. My mom said this is a mistake. Well I bought some rum and im sipping a cool rum and coke, should I go in tomorrow?
