<human>: Could you distill the essence of the text into 1-3 sentences?

I've been in class with the same group of people for the past three semesters. There's this group of 3-4 lacross girls that are always together. I'm usually the quiet one in my classes and I just recently made my first friend out of the group and I've come out of my shell a little bit. I've done presentations in front of these group of people that have been pretty bad. I was going through a rough time so my self esteem was really low. I'm still working on it. 
I've never sat next to her and she's talked to me once and that was when I walked into class with crutches after a surgery. She asked what happened and said hope you feel better. Yesterday we were on a tour of our school facilities for a class project and I said a joke next to some people joke in out group and I think she laughed at it. On Monday out class is going to a Major League Baseball game to do some marketing for class then watch the game when we're done. Should I talk to her then? I have no idea what to say and I know if I fail everyone in my class will know about it and I don't want to come off as a creep as I usually feel I do when talking to girls I like.
<bot>: like girl in class, never talk to her. Don't know what to say and don't want to come across as a creep.
