How to deal with anxiety?

I've been trying to keep up with my coaching but fail to do so everytime. I am genuinely trying, I'll admit I didn't really study during the initial months of 11th but now I've been working hard to get back on track (currently im focusing on nlm and wpe, mostly nlm i know some basics of kinematics). With each second passing I feel like I'm running out of time. I have terrible anxiety and dont have anyone to share my feelings with lmao

How do you guys cope, I feel so lonely sitting in my room all day

Idk wth I'm talking about thanks for listening to my rant ig :)
