Calling off work

So I want to call off work tomorrow for the first time at my new job I've been at since June. It's been so busy there and I really could use the day to myself to relax and take a personal day. The last few days I worked have been terrible because it's so busy and I usually don't ever get to sit down all day, 12 hour shifts.

It'll also give me a 4 day weekend so that's definitely on my mind too. Does it make me a bad person to call off every few months to take a day to myself? 😅
