It's normal to be confused and have conflicting feelings during a time like this Silly. ie. hopeful and scared and hurt and angry. I honestly would feel the same. It's very difficult to deal with people trodding on our emotions, especially when we put ourselves out their in all our vulnerable glory only to feel as if we've been victim to a sick game. I've been there.
Fortunately, you're forgiving and kind. I would suggest to have a heart to heart with your friend (can be on the phone or via IM), explain how her actions made you feel...if she made a sincere apology I think that's worth something. If she wants you as a friend, however, she'll have to be held accountable too (take responsibility for her actions). If you don't know how to go about this, ask a friend or consult your T. How to effectively communicate your feelings without bringing more emotions into play? How to maintain a friendship with fear of the same thing happening again?
Definitely talk with your T, write it in your journal if you dont know how to describe it.

Sending much love to you.
Feel free to PM anytime.
