who is 100% your friend ? i really don't know anymore

I'm so tired of having to deal with things that don't have anything to do with me.
I love my friends , i really do, but i'm starting to realize that some of my closest friends are truely selfish and as the time goes i get even more aware that they don't like me as much as i like them . i guess i just have to deal with it.
yesterday's night was awful . i had a fight with one of my closest friends, i argue with another one of my closest friends, my bf had a date and she wasn't able to go and it was heart breaking to her :\
i really miss 2010 already, i want my old school , and my old and best friends
