I Have been in this situation.

And it went really well. She was very happy for me. She actually gives me tips and explains things to me a bit more, and since I'm in college for it and have a few years under my belt already it makes therapy a lot easier I think, when having to discuss her boundaries etc. She was really proud and happy for me. I think your T would be too.

I wouldn't worry too much about it, cause alot of T's have Mental illnesses as well.
