Hi Ryan358,
Welcome to PC. Sorry you're feeling so stuck. Einsam post is great and very apropos. I don't really have much to add, except:

When you're on the floor, can you sit up and do something physical? I used to toss a ball overheard from one hand to the other. At one time, that was the only exercise I got.

If you are home schooled, can you look into social groups with other home schooled kids?

Are you seeing a T or PDoc? It sounds like you would benefit from having a professional assess you. Actually, you could start with your primary physician, who can rule out a physiological reason for your malaise.
