(((lifelesstraveled))) I can relate all too well. My biggest fear in school was being called on by the teacher because my mind went blank and I didnt want to look like a fool in front of all the other students. I wiggle my feet in bed as I fall asleep too (I hadn't really thought of that as a possible symptom until you mentioned it). I also tell myself stories to fall asleep: ones that evolve around being wrapped in a comforter and feeling really tired, otherwise my mind will go from one thought to another, and i'll never get any sleep.
I'm also undiagnosed. I have been tested for ADHD but I won't know the results until Dec. 10. I think you should explain to your T (if you haven't already) that you want to be tested for ADHD. They should be able to help you navigate that process, even if they don't agree with your decision. I wish you the best of luck! Keep us posted!
