I read over some of your posts and it sounds like you've been working really hard and want to work really hard. Maybe you see the recovery that some here are enjoying and want to have some of that too. I wish I could give you something based on my past experience, but I have nothing. I do know that there was no part of my trying to get better that was easy. Actually, most of it sucked! The only thing that really motivated me was that I just couldn't take feeling so alone and afraid of myself and other men anymore so I pushed forward and keep pushing forward.
I gather from other posts that you trust your T. If she is recommending it then maybe it's a good thing. Do you have to stop seeing her?
I hope you are able to ask more questions so that you can feel comfortable making the decision. I also hope there are others here that have some first hand experience to share with you.
What I can give you is words of encouragement as a fellow survivor. I care about you as I'm sure others do that have read your posts. You seem like you have made progress with the help of your current T and hope she is able to point you in the right direction now.
