Having trouble making friends at college?

We've only been at college for two weeks and everyone around me have good friends that they just met already. I've hung out with a few but because I've always struggled to have a social life I don't really know ht to say, most of the stuff they talk about is rubbish anyway and don't even try to make conversation with me anyway but I do try even though im not sure what to say and act cool.

Today I hung out with two students on my course but whatever I say either comes out too quick or I just confuse them because I have to fight to be heard since one of them is chatty anyway and won't let me get a word in so I just feel like their shadow and I feel really insecure from past experiences of meeting crappy friends and I suffer occasionally from panic attacks and anxiety so nothing people say go in because im nervous.

I usually just read a book during break because it was the same story at school but I always just wanted to fit in and enjoy my time in college like everyone else.
