Feeling guilty for asking for days off???

So I’ve always had this problem at my old jobs. But i actually have a lot of time for PTO at this job and I do want to use some of it, the problem is I always feel bad asking for the PTO. I know it’s stupid but i don’t know how I would ask for the PTO in the first place, it’s not for an appointment it’s for mental health. I just need a day off.

Like a three day weekend. I wanna be ruthless and just tell them I want a day off, for mental health. And that’s it.

I don’t think my supervisor would mind, but she has moods. Her lead has told us that she recommends we take off whenever we need to when we get burnt out. But I just feel guilty for asking. 😑 what’s the point of PTO if I feel bad for using it for PERSONAL time!!!
