Absolutely Agree with u, if there is such a drastic change in her personality there has to be a reason for it right, but no one is understanding that, no one just wakes up one morning n decided 'oh I'm going to react to everything in a hyper way today' if they all are her friends as they claim to be, shouldn't they find out the reason why she is upset. And aren't friends there for u to snap at when u r in a bad mood. I know I snap at my friends all the time when I'm in a bad mood after having a fight with my mum or someone. But My friends know thats not how i normaly am, and if im behaving in a different way, there must be a reason for it. That's a NORMAL HUMAN BEING, if we are upset because of one thing, it automatically spills over to the other things. It's not that we can be upset one min n then forget it all when talking to someone else
