adderall or similar meds mog every other medicine when it comes to executive dysfunction. Depression commonly finds roots in adhd & learned helplessness so that might relate to what you're feeling. Can you see a psych about meds? I'm in a similar boat rn since i cant until what could take abt 7 months. I find caffeine (with regular tolerance breaks) acts as a minor stimulant (which is what most adhd meds are) and helps me in a pinch when paired with L theanine to prevent anxiety lol, though it works differently in everyone
outside of that all anyone can reccomened is just fighting off depression/remaining healthy. if you have nothing to look forward to every week youre gonna end up killing yourself, try to hangout with friends often and have them pressure you to focus (study groups n shit, idk i dont have friends so i cant say how well it works but ive heard it does) and do regular health shit. Vitamin d deficiencies will amp all your symptoms to dysfucntional levels, get bloodwork done
at the end of the day no drug routes dont perma work with modern society or school unless you live in the middle of the woods like ted k jfl
