Why can't I just do the things I want to do?

Every single time I'm busy with school and just have absolutely no time to do anything, I procrastinate doing my work/assignments (basically anything I actually have to do). and I daydream about what I actually could be doing, like reading, watching a movie, baking, drawing, you name it. I have so many ideas about what to draw, bake, or sew. I know exactly what I want to watch and read. But because I have other things to do (but don't want to do them) I don't let myself make that drawing or play that game, I just doomscroll on my phone, which is a huge waste of time and isn't actually what I want to do. 

And then when that deadline is done and I basically have like 3 days before the next assignment starts, I just…sit and wait and do nothing AGAIN! I basically don't feel like doing anything. I have no idea what I want to watch, play or make! and I wasted that time, and when I'm back at work again, I get mad at myself for not doing anything again. I have no idea what is wrong with me, but I really need to do something about this. 

For now I'm just going to force myself to watch a movie and see if it changes anything…fingers crossed it will.
