GROUP- TEAMWORK

I continue having a busy day at univer and the subject which i have studied that requests me to have a group. i imagine that i have good group but how sad, they don't like and just want to work without other members. i feel sad and worried if i can't have a really group at student's life. i want to act and do well with teamwork because it is very important but... Perhaps all is my mistake. Yes , my mistake and i don't want to blame anyone!!!!!Group, Teamwork often make me confused and disappointed although i have tried a lot.hoping, yes, continue hope a bright future with teamwork but i don't know how it will come?! not very happy today! boredom at here, my class!?!
