Procrastinating

I am procrastination. It's not that I procrastinate anymore; I have become procrastination itself. And I don't even mean it, I try so hard to focus and do homework/studying a bit that I just can't. I just can't. I try to sit and stare at the book that is in front of me, but before I even notice, unconsciously I have risen from the chair and I'm heading to the stairs, to have a full guided tour by myself through my house, that may take 5 minutes or 3 hours. I just start wandering around every hallway of the house while I think about everything and nothing at the same time, and when I realize that I should go back to study, I aslo realize that I have spent more than half an hour walking around some random room.
When I go back and I try to focus, I just can't. Sometimes I just repeat what I just did (having a looooooong walk), or sometimes I stare at the book while I get anxious and I end up throwing the book away (like in a literal way) and
a. Having an anxiety attack.
b. Hating everything and being pissed.
c. Both.

I don't know. It's never been like this. It has gotten worse and worse over the year. I remember of myself in of 1st of ESO, when I just happened to be a lazy human who wasn't much interested in school, but I had no problem focusing on homework. But now, it's practically impossible. I started to have this problem in 3rd of ESO, but I managed to overcome it. It was hard and I failed a few subjects because I just couldn't study without having a rage attack (books, notebooks and pencils flew all over the room), but I ended up managing. It wasn't as bad as it is now.
Now I spend like 2 hours doing something that usually would have taken like half an hour. And it's not a way of speaking or an exaggeration. The last few times that this happened, I counted the time and it was that. 2 hours of my life wasted away forever.

I don't know. I don't know what I'll do. I'll probably end up failing everything because I can't focus on anything. Well, I guess there's not much I can do.
