I know how that goes, esp. if you are really connected to your T -- I cried and cried the first time I cut after my last long-term one (I have had a few quick duds since then) had worked for months to help me not to anymore. We talked about it and he said he was surprised that I was more worried about letting him down than I was about myself.
I'm sure your T just wants you to be OK, and surely she knows setbacks happen. Just focus on how long you went without before and know that you can do it again.
