Awkard..Me? No.

My sister told me today that she doesn't think i should go to a party tonight because i am awkard and she worries about me and thinks im not having fun, cuz last night she didnt think i was fitting in. Well i wasn't but it was because my friends went to smoke weed without me and and then went to chick-fil-a without telling me and ditched me. I was having fun with other friends but i felt really upset they left because i cam with them, so when they came back i didn't know how to excatly act. Also i am suffering from a dislocated rib (recent popped back into place, but very tender and sore), floating rib, and muscle sprain, which i had done to myself by accident during our first volleyball game...four weeks ago...i just found out it was as serious as it was three days ago...i have been playing ten volleyball game, conditioning, carrying a heavy backpack and not treating it whats.so.ever and irrating it more for four weeks. So i'm sorry i was not in the mood to be all happy go lucky. She sudtly told me not to go tonight, even tho i have been looking forward to this for a while now and i feel so sad and alone and very very very awkard now.... does everyone think this of me now?
