How to make friends?

Hello! I'm Ghoul and I'm 20 years old.

Because of things that happened I had a very hard and weird time growing up. I struggle with depression and anxiety, which were much worse when I was a teenager. I'm putting my life back together now but I still really lack social skills. I take classes with people within my age range that have all dealt with something in life, and there's a guy I'd really like to befriend. We have similar interests so we talk about that, but I don't know where to take it from here. Any advice? I don't want him to think I'm creepy if I act too friendly or something.
