guys, I think I'm starting to have a problem..

pretty eye catching title, huh? Anyway, I do think that I'm starting to have an issue with my shyness. I have been coming out of my shell a LOT this year, and I'm able to make friends and everything but I'm still much too shy to even tell someone wearing an MCR shirt that I like their shirt. (and there's this guy who has all these MCR shirts and I really wanna talk to him but I'M WAY TOO SHY!!)
So, do you have any advice? I've heard the 'just push yourself to do it' but sometimes that's almost impossible for me!
