Alone, I have similar issues with women. I want to be close, but I'm afraid they'll be disgusted by me. For me the transference is a lot more manageable working with a male T. It's still slow going though.

Have you told her about your past issues/desires towards women? (And no, I don't mean anything erotic, just the desire for closeness). I think you should tell her how much you are going to miss her and how much you want to ask for a hug, but that you're afraid she'll say no. Who knows,she may surprise you. In my experience Ts don't respond much or at all to hints. They want you to own your needs. And even if she does say no I think the asking would be a huge step for you and would help you feel better in itself.
