Sleep schedule and mental health

WARNING: May be potentially triggering. (My mental health is not very good).

Usually, I sleep from 1 am to 12 pm or so, but recently I have been trying to wake up earlier-- so I sleep from 1 am to around 9 or 10 am! However, today, since I have in person today and tomorrow, I slept at 1 am and woke up at 5 am so I only got around 4 hours of sleep. I am very tired now, I kind of want to sleep and kind of don't want to. I have a lot of missing work as well which I should probably do.

Edit 11:19 pm:

So, can we talk about those assignments I didn't do? I never do assignments on time. It's always turning them in at the last second or turning them in weeks later. I really don't know how my teachers put up with me being so stupid all the time -- if they even put up with it at all. I really, really hate school. It's like seven hours of just nothing. Why do I have to go through it for any time at all? Last week when I stepped into school on Monday and Tuesday it was like a switch turned on to suddenly make me sad, and I felt terrible all the way up until school was over...

Well, at least it's a bit better now. I don't feel terrible every time I walk into school at least. I think that my mental health has been declining recently and I have been feeling more and more terrible... I am a bit scared for my future. I wonder what I'm going to do for college. I have no idea what I'm going to do for college. So that is why I am wondering about it!

I should go to sleep. In person school is tommorrow.
