Feeling okay about mental health days?

Hey all,

How does one feel okay about taking mental health days? I always feel like shit about it because I lie that I'm sick rather than telling my employers I'm autistic and have bipolar 1 and OCD (I work with kids and worry they'd think I'm unsafe or something)... next year I plan to change my work week to 4-day weeks, but it's still really tricky yk?

In the meantime, I probably take like 2-5 mental health days per 20 work days. They're unpaid, since I've long used up my vacation, but I still feel really bad about it. Thoughts?
