What she said about "she has never seen this before in all her practice" or whatever it was really struck me, I would be very demoralized too to hear that. I'm not surprised by your comment about feeling unloveable by anyone at the beginning of this thread. I would suspect there is a close connection between those two things.

The phone thing doesn't seem entirely fair either as others have pointed out. Perhaps she is feeling frustrated that, by looking for reassurance, it's sort of like you're questioning her interest and commitment in you over and over again. And every T wants to believe they are a very nice person who is magically can cure people with their empathy and support. So the fact it's not working is maybe pissing her off. But that's NOT your fault. It's absolutely not and the more she gets "sarcastic," as I'm sure you're aware, the more she's giving you actual, legitimate grounds to doubt her.

I guess one thing I wondered following this post is how you feel about all this, if at some level, you'd be relieved for her to let you down once and for all and end this relationship. I know for me that would be in the back of my mind and might influence my feelings about calling in the future.
