Give me your opinion!

I had 7 friends all of them were like sister to me but then like 2 months ago they started cutting me off of everything I noticed it didn't make a big deal out of it, it continued and I asked them and they found thousands of faults with me which some of my other BFFs never noticed 1 month ago I went for a trip after 3 weeks when we came back they just broke it to me that they don't wanna be my friends the thing is when I was on the trip I realized that I don't wanna b their friends either but when they broke the news to me I was hurt REALLY VERY MUCH!! now that I see them they have changed A LOT and in a bad way (they have become self-centered and selfish, they treat people like crap, all they can talk about most of the time is themselves and what they will do, and how much and why do they hate someone!) no one in our class likes them I don't either!! I am happy that our friendship broke but I still feel sad sometimes.
