Okay, I can understand your frustration, because I'm on the same boat. I don't even know if I should give you any advice, because I myself am in the worst stage of my life.

But, still, firstly, relax, calm down, stress will make things more harder. I know people are giving you advises to go and see a doctor but if you have the same case as me(that is no one is really aware of you going through this shit). I mean I can't just go to my parents and be like "Mom, dad so I have or feel like I have this disorder called MaDD since my fucking childhood and I just recently found that out about myself, no no don't worry it's not schizophrenia , it's just I make imaginary people in my head and talk to them for hours day and night. Let's go see a doctor." What I mean is, a lot of parents don't pay much attention to mental health issues(maybe your parents can be different, if that's the case than you're damn lucky), I just told my mom if I should consider taking pills so that I can concentrate better and you know "be here". I'm telling you she was so much shocked. She started telling me what chapters and subjects are you feeling difficulties in and we'll try our best to hire new teacher and all that shit. (Damn I hope you're getting what I'm trying to tell you, in no way I'm trying to demotivate you to not go and talk with parents or doctor but we all know everything is not very easy, right?)

So, I tried to think of the time when MaDD was not a problem in my life. That was when I was a very little kid, probably 5/6/7 years old. Other kids in my class used to have fun, talk and not pay attention to classes, but I, used to listen to the teacher, write my notes, study. Why? Because I used to think, that my parents are checking up on me from the classroom window. (Yeah, don't judge me) So yeah, imagine, someone checking if you're studying or not, what you're doing at the moment, will you daydream then? Will you try to act out your daydreams, run, pace in your room? I'm not telling you to develop paranoia, but, maybe in this way you can try to be aware, of what you're doing, because as you'll start to daydream, hours will pass and you won't even realize it. Try to see yourself from third person perspective, or maybe someone, who has a value in your life, will you waste your time? Daydream, making weird expressions? Try to give it some time and thought.

Also, I feel like, this sub is my family, the people here, are probably most relatable people I will ever get in my life. So whenever you feel alone, you can come and write your progress, or feelings here. I mean I'm no one to tell you all this, but I know how much it sucks to be alone, with all the problems in your head, no one knowing what you're going through, especially when you're a student. Sorry if I confused you anywhere as I sometimes suck to explain myself, but I felt like writing this, so that I can process it myself.
