sounds kind of like you're going through the stages of grief.. denial (which happened right after the call), and now anger, depression (the sadness), bargaining (the desperation), and acceptance (which would come with a bunch of fear that the relationship might actually be over).

i don't have anything to say other than that, and: can you call her again? i think that might be a good idea, but not if it's going to make you feel worse.
