Maybe you should try talking to your friend to find out whats going on.
I moved away 5 years ago from what I thought were my best friends.
Needless to say they don't call me. Except one very special one. And her mom has cancer right now and they don't expect her to make it another 3 weeks.
Her bf is in the hospital. But she was there for me when my mom died a year and a half ago. We have a special bond that when anything major happens we are there for each other. I love her like a sister.
You never know this may make your friendship stronger. If it was meant to be it will turn out for the best. I wish you all the best. I know how hard it is to be on the losing end. You feel like your all alone in the world. You want the world to stop but it just keeps going. But if I were you talk to your friend. She could feel the same way. You won't know till you talk to her. Your in my thoughts and prayers.
