What am i doing wrong?

I'm what people would describe as a "wannabe people pleaser" i try to get everyone to like me and dont take rejection well some people say im too nice. I been at an acting school for about 3 monthes now it seems like no one wants to be friends with me as much as i try. I guess they are just not interested in me because basically everyone else has bonded a lot all ready. What am i doing wrong? Is there a way to help me make new friends that isnt the try to talk to them and be nice advice?
