Wow. Sounds like you wrote this for me. Secondary social studies teaching degree...with an emphasis of psychology. Who would have thought I would find out 10 years later I have Bipolar 1. Same thing, I in the top tenth percentile of college professors and feel like an 8th grader now. My wife and kids say I repeat words trying to spit them out. Just keeps getting worse. Set up a lunch/business/interview meeting with a guy Wednesday at 12:30, 30 miles away... almost got there, looked at my phone and its Tuesday. Where's the marbles going?
