Girl in my group

I'm supposed to be writing essay for my anatomy lectures, but I needed a break lol

There is a girl in my group at the university. The prettiest one I have ever seen. She got there later, at like second week of the semester, and I was one of the first people she talked with. We have all the lectures and other classes together. I want to get closer with her, but despite my meds I'm still insanely socially awkward and I don't know how. I try to sit next to her at lectures, be her pair when we have to get into those and be first to answer her messages on group groupchat. But it's not enough and I don't know what else I can do TwT

I think she likes me as well, but I might just be delusional. I don't even know if she's single or even sapphic

Last time I had a crush on someone it was 2 years ago, way too long break
