I'm 17 in England at a high school. I really have no idea what to do with my life. I have really bad social anxiety and social skills, from years of nothing but video games, anime, porn. I have a non existent relationship with parents and no siblings and like 1 friend from world of warcraft.

About 4 months ago I quit everything then focussed on self improvement. I did nofap for 70 days, read books, learnt meditation, studied a lot there's nothing left to study I'm getting A*'s in every subject 4 months before the exam, lifting, cold showers etc.

After doing all this, my social skills are still dog shit and my mental state is useless. I hate going to school, not because 'it's boring' it's because I'm around retards who have no idea how the world works still plugged in. I can accomplish any task I set my mind to except improving social skills, I can do anything I set my mind to, I've been social conditioned so hard to be a worthless beta it's impossible for me to improve social skills.

I have 7 months until I go to university and I want to fix up my social skills, as well as my mental state so I don't go insane. I have no idea what I should be doing in the mean time for these 7 months to improve myself further. I don't care about my present self, I'm willing to sacrifice my comfort in order for the future when I go to uni and move out. If I can't fix this I'll just go back to playing video games otherwise it's just mindless suffering.

TL;DR 7 months until university, 0 SMV, 0 social skills, high intelligence, high willpower, high discipline. What can I do to improve for uni?
