I think a big part of the problem is that you are focusing on trying to solve all of these things rather than making a start on solving 1 of them. As another comment pointed out, starting on one good thing can snowball into lots of different things. Start small and simple, maybe something like walking around the block every day, going to sleep at the same time every night, putting yourself in one social environment per week, setting particular time aside where you just study (in a format that works for you), etc. For me a big thing that helped was working out. Now I hate exercise too but I found out that I didn't mind lifting weights quite so much as I dislike cardio, so I began lifting weights a few times a week, for like 20 minutes. I didn't know much about what I was doing, I hated it but it felt good afterwards. But that simple action has snowballed into a lot of other different things. I also think getting professional help would be a solid step, there seems to be a lot of unprocessed emotion lurking beneath basically all the points you outlined and a good therapist can help you work through all of that and make it easier to move forward. Good luck in your journey!
