i am so lonely right now :(

i feel i am not close again with my best friend because we just had a new girl in our group, and they become close pretty fast. it's kind of awkward for me to meet my best friend now, when we are talking it's not the same anymore...
one of the story is, we hv a project, 3 of us, both of them are smart n i am just average. they don't really count my opinion and give me the easiest portion to work with, truthfully i am hurt. i just want to go away and stop going to campus :(
