18M, very socially anxious and trying to hint to someone that I like them, any advice?

I posted this to r/dating and it got buried so I expect it’ll get buried here too but I’m still gonna try

I don’t have a lot of flirting experience, previous relationships I had weren’t very serious and I have really bad social anxiety so I’m constantly worried about messing anything up. I’ve been texting a friend that I like, I’ve been getting very good vibes lately off of our convos, they usually go on for a while and it feels reciprocal I guess you could say. It doesn’t feel one sided.

Anyway I’m trying to drop hints that I’m interested in her, but I don’t really know how to do that without coming across as weird.
