You might need a medication adjustment.

Even though I don't have fog from meds, my verbal memory is shot. At work I take time to rehearse my dialogue in my head because I cannot speak on the spot without stammering. It's also part of the reason I have social anxiety. I have my good and bad days.

I agree with BipolaRNurse that smartphone calendar alerts are a good idea (I use them to remind me to take my meds) and leaving yourself voice recordings with details can help. I use to work with attorneys that walked around the office all day with their hand-held recorders because no one can remember it all. Hang in there. Hope things go well for you at school and work.
