Touch can be healing, and it sounds like this is what it would be for you if your T touched it in the gentle, loving way that I'm sure she would. I think that T's generally have outlined boundaries, but they are flexible to accommodate extenuating circumstances or for each unique person. So even if your T has a no-touch policy (and it sounds like you're not sure if she does), in your case there is a clear reason for her to go against that. I agree with Freewilled that it at the least, it can't hurt to talk to her about it. And you can explain to her what it would mean to you before you ask.
