((((((((((((((Dorine)))))))))))))) I'm so very sorry that that happened to you.

You are so brave and wise to go back to another T.
For me, the only way I'm able to see if my T is safe is time. It's taken a few years (we don't trust easily...) for us to start to trust and it still seems like a lot of things make us back up and have to think through the safe thing again.
My advice is to just give it time. Your new T might have to prove that she is safe and trustworthy but if she's a good T, she'll be up to the task.
I'm glad you're here. There are a lot of really very understanding people here. I hope you will find the support you need.
Take care and welcome to Pysch Central.
