Do I have a crappy best friend?

Sounds like it! She certainly is not empathetic or sypmathetic. Sounds totally self-centered and could care less about what is happening in your life. Maybe you should find another "best" friend. Best friends are always there to support and encourage you, to share your joys and your sorrows, to pep you up when you need it and put your feet on the ground when needed. Sometime they are there to listen and sometimes to advise. This girl can't do any of that. I'd lose her!
