I trusted my T more than I should have. My mistake. All my instincts were wrong about him. I am STILL mourning the loss and the error in my ways to have trusted. Sometimes we cut people off for a reason and it may be very valid. My T lied to me .

I'm not saying not to trust your T but be very cautious that he is on your side and is supportive of YOU. Mine gave up my confidence at the drop of a hat because he was lonely and was trying to impress a pretty client with his "insight" into my life. I could say a lot more but I'll leave it at that. His judgment was way off the chart.
You can always try trusting your T (or anyone for that matter) with little things first and see how it goes. Test the waters. See her reaction to your small revelations and ease into more serious ones. I have cut off people in my life for a reason, not arbitrarily. I'm sure you had reasons for cutting out the other T's or people in your life too. Do what you believe in for yourself.
