Firstly. 2yrs. For that type of work is nothing.
I didn't even really begin for the 1st year and by the 2nd year I was just as "in it" as the 1st year.
Sounds like your T really doesn't understand it. Doesn't have that inner knowledge that is vital. Thst would lead to you being retraumatized. But how can someone know this if they've had no better experience of a T that is skilled, does understand the work. Does have that inner knowledge. They can't. But from what you've wrote I'm telling you he cant help you and someone else can.
