i'm just like you. i am an inrovert that even after one day just being between people i just get cranky and really irritated. making friends takes time as well. just choose a person who seems friendly and you will like and try to spark a confersation and try to get back to them if they don't think your annoying. and after a while alot of friends of them will come and talk to you as well. (that happend to me :p i have some friends and other friends from them who just came up to me) making friends is hard but you need to make a step forward otherwise you will never make friends (i learned that over the years) mabey it's hard but you'll learn soon enough and you will feel comfortable around them as well. just try those things and mabe that will help you out.
(and boyfriends??? )

A simple PM or comment on their newsposts might help spark a friendship.

I know that. It's just that I've really never been able to make a good friendship in person, sadly.
