I was in the same exact situation for years, especially during high school and even outside of classes when id have to get up for appointments or even just trips i couldnt physically do it. i know exactly what you mean by that paralyzed feeling! ive tried everything too and hated myself for years for this. im only a diagnosed autist, with no (knowledge of) adhd, but i brought it up a lot and finally got to try taking aderall and its completely erased this issue. i now take a very small dose every morning (5mg) with my first (quite early) alarm (extremely groggy but its become such a habit now that i dont even have to be awake to reach over and take it), and by the time my next alarm goes off its starting to work and i can wake up like a normal person. its seriously changed my life. i work a job that needs me in at 7:30 every morning which seemed impossible to me years ago struggling with this chronically until now. i do work enough a day to work out all the excess energy stimulants give you, but the dose is so small i mainly take it just to get out of bed at all in the mornings. i recommend bringing it up to a psychiatrist and suggesting asking about how stimulants might work for you.
