The real answer is you don't need to overthink it. Think less.
I'd never be able to talk to her because I have a mental disease that makes me overthink thinks to the point where I look like I'm brooding all day, and no one wants to be around me.
You sound normal so if you're not easily discouraged and can say more than a few words without getting flustered, just say "hey I've seen you before" and take it from there if she sticks around after that
