I'm dyslexic without any meaningful help. School made me hate books, studying, knowledge. I wasn't a good student. The only reasons i didn't fail was because the teachers liked me and generally everyone got a good grade. Only after finishing highschool i started loving reading books and then learning. It seems that the fire was there, it became very weak, but didn't disappeared.
The internet saved me. It gave me an environment where i was able to understand that many things in my life weren't normal. Gave me references. I wish was like the kids who wrote code from a small age and grew there knowledge and curiosity, but at that time i couldn't for many reasons.
Currently i'm in a place where i fight my old past and mental health demons, trying to learn how to be organized (todolists, obsidian journal, calendar, etc), making new habits and tearing down old was ones, and find resources to teach myself how to study, especially how to study with dyslexia and mental health issues.
So my general advice to you is to minimize the activities you devote attention to. Focus on your classes/studies. Find study groups, or organize them yourself.
Avoid parties/partying. Avoid romantic relationships.
Make a sleep schedule and stick to it. Get fresh air. Engage in outdoor activities - walks, biking, pickup games. Do these things indoors if you can't do them outside.
I'm not sure what you mean by "mental health demons". If they're serious issues, you probably need professional and/or group help with them. Do whatever you need to do to keep them in check.
Good luck
Edit: Stay off social media: FB, Twitter, IG, TikTok, Twitch, etc. Youtube is okay if you restrict yourself to videos that assist your studies.
Avoid political and social issues. Keep your eye on the ball.
