I think it's important to be honest with T, for them to have a full picture. I'm going through this now. I have not wanted to bring it up with new T, would have preferred to completely leave out the DID stuff and not mess with it. Always running in my life. Moving. I've worried about the can of worms too. But I really hope to heal this time. I hope that for you too. I would think honesty is the best thing with your T. It's a pretty significant issue, whether in the past or present.
