I think you nailed it when you said that it's back because what is behind the ED is not being resolved... I think that's a huge step before you can take away that crutch, or you end up finding something else... I think if you are honest about it and can communicate with your T about it, s/he will take it better. I know my T was supportive when I wasn't ready to quit yet, and she helped me lessen the damage when she could. then it got to a point where I HAD to stop, but she helped me through that too. I think the more a T feels comfortable dealing with SI, the better they take it (less panic on their end... they are only human after all)...
