The reason I felt I needed to tell my T when I ended up sat outside her house one night was because I felt that for me, I had gone a step further than I had wanted to. I had told myself that I would do my best not to do this with this person. I had told my T that I would do my best. I did do my best but I still ended up there and I wanted to tell her because it didn't feel right to keep this information to myself. That and the fact that by telling her she could more easily see how bad things were for me that night.

The googling though, I have not divulged and at present I have no plans to.

You have to do what feels right for you.
