How do I get rid of laziness? I'm so damn sick and tired of this laziness!!!!!

I want to play games, do my own things, but I'm too lazy. I'm too lazy to do almost everything!!! I've been dealing with this laziness for almost 3 years now! But it used to be worse—I could literally fall off the bed onto the floor, and even if it was uncomfortable, I would just keep lying there because I was too lazy to move. I would only get up when my mom called me over or when someone disturbed me (for example, if my sister asked me to play with her). And sometimes my headphones are lying right next to me, literally right there, and I want to listen to music, but I won't pick them up because I'm too lazy to just lift my arm a little bit! I don't know how that passed, but thank goodness it's at least gone now.

But I can't fulfill my own desires. For example: I want to play a certain game, I want it so badly, but because of laziness, I can't even launch it. I don't know how to explain it, it's like someone put 100000 kg on top of me—metaphorically speaking, I don't feel the actual weight, although I'd die under that kind of weight... But you get the point, I hope. Inside, I want it so badly, but on the outside, I don't.

Like, almost a year ago I wanted to make some friends, and I wanted to post in some subreddit on Reddit saying that I want to make friends, but... I realize that because of laziness, I won't be able to communicate with them; I'll only be able to do it occasionally, and because of this, I still haven't brought myself to do it. I've been literally lying on my bed for almost 3 years just changing my posture. Sometimes, very rarely, I get a desire to do something, and I actually do it, but after a few days or even the next day, it disappears. And honestly, realizing that I wasted almost 3 years on absolutely nothing makes me want to cry. I could have done so much during this time, but instead, I'm doing nothing!!!

My laziness makes no logical sense. Right now, I'm not too lazy to write this, but sometimes if I want to write something, I'm already too lazy. I'm too lazy to brush my teeth, I'm too lazy to wash myself, I'm too lazy to pour myself a drink into a glass, I'm too lazy to put already prepared food onto my plate!!! I'm too lazy to do basic things and sometimes I just don't do them; I only do them because I was forced to or because I'm already way too hungry. I don't know how to force myself, I can't! I can't force myself to do even the things I want so badly, so I just lie there and feel sad that I'm not doing it, and that's it! This whole thing sounds like complete nonsense! I mean, like, I can't force my body to just do something—it sounds strange and even stupid.

If you have any advice or something like that, please share it, maybe it'll help. Thanks, and sorry for taking up your time ;3
