In extreme need of help rn 😭

This may sound pretty pathetic but recently I have been so stressed about school and home and its got to the point where I kinda need some help with how to get through the school days.

I get quite upset each night when I know that I don’t actually have anything to be upset about; its weird and I feel stupid because of it. Sometimes I feel as if I could just occupy myself by just starring out of space, whereas other times, I feel like I need something to do because otherwise I will start overthinking. I don’t know what’s going on with me. Is it because I’m stressing or is it something else? I’m only 15 so I’m extremely confused and my parents have a lot going on at the moment so the last thing I wanna do is put pressure on them. I hope someone can help me?! 😕
