It is a common thing to push away the very person who can help us. You should not be worrying about your T and his health or involvement in your therapy issues, that's for him to maintain.

Try and reevaluate the true situation: does he do anything that is out of line, across the ethical guideline? does he say or ask anything you feel is untoward, and does he not stop asking or pursuing even after you've told him to? is he intruding into your personal life, at your home or work, by calling or writing inappropriate things to you? I realize there are some ppl who shouldn't be counseling others, but is your T really one of them?

It can be difficult to understand boundaries if your life prior to therapy had no boundaries or ones that always "moved." I don't know your situation. Does the T have a partner or someone you can inquire about his methods?

Discuss these things with your T. Ask him to state where the boundaries are, and give him the opportunity to show you and even readjust them, should you need stronger ones.

Don't just push him away. Being afraid of someone who knows so much, who can hurt or crush you (you feel) with his very words or actions... well, that's ok, it probably kept you safe in the past. But being afraid of someone who is there to help you, truly, and someone you have given trust to, won't help you work through this. The T needs to model good behavior, and as you become afraid, help you work through it to see that there are ppl in the world who are safe.
