Can you request a vacation day off?

I have disclosed to work, so when I call in sick (which isn't often), I don't worry about it. I also work 60+ hours a week, so I don't give a crap. All my work gets done, and I"m meeting my revenue goals. So they can suck it. Lol.

Disclosing can work for you or against you. I think if you do it properly, very formally and business-like, and also approach your illness and need for time off very formally and business-like, and not like asking for a favor or anything, it can be done in a way that doesn't hurt you. I find that a lot of people do it like they are asking for a favor. But it sounds like you are an upstanding and productive employee. Work has to make a reasonable accommodation, and it does not sound like using your sick time is unreasonable. That's why it's there.

Get a note from your pdoc or T if necessary that says from time to time you may use accrued sick leave due to your disorder.

I would disclose if I were you. But do it very formally and with a well written letter. And DOCUMENT EVERYTHING.

Good luck,
