It is completely understandable that abuse by a T would make a person feel as if it would be way too risky to trust again.

Silenthill, you have done an amazing job:

You recognized the abuse and unethical actions of your T. That took a lot of courage, to allow yourself to see her actions for what they were instead of what she tried to convince you they were. In the end, you are one she just couldn't fool.

You took action to defend yourself, to recover your losses, and to protect others by letting it be known publicly what had happened. That takes tremendous courage too, putting your own personal experience out there.

The feelings about not trusting again I think are about the feelings about how difficult this process is to go through. There must be many feelings about it that you have. Wanting to protect yourself from this ever happening again, it seems like never trusting again is the best protection. That makes so much sense that you would feel this way. This T was not worthy or your trust.

Yet, trusting again and finding the T to be trustworthy=worthy or your trust, would be a way to heal the wounds left by this experience. I hope you give yourself this opportunity. I wish you had a trustworthy T to help you right now through this situation, and beyond.
