In need of advice!!

Im a really shy and nervouse person and sometimes I just want to break out of that habit but I can't. So I need some advice from anyone. I go to this community college and there's different ethnicities and cultures. I always see different people but this semester I saw this girl with a purse or bag of the Japanese movie My Neighbor Totoro. Its an amazing movie and well I couldn't even speak up and at least say that I know who Totoro is. And just a couple of minutes ago I saw this girl with a picture of this handsome man clipped to her backpack, and I couldn't even say, "I know or also love GD" So if you have any advice please tell me. I need to learn to SPEAK UP and be able to say that I ALSO LOVE KPOP. Lot's of KPOP groups out in this world!!!
