You, unfortunately, have a very bad therapist who doesn't know her boundaries. I have issues with trust as well. Trust has to be earned, not just by friends but by our therapists as well.

Don't give up on therapists. There are very good ones out there. Ask your GP for some suggestions or go on Yelp or Angie's List. Write down everything you need (not want) in a therapeutic relationship. Call each of the suggested therapists and ask them questions to determine if they meet your needs.

As I have worked with my pdoc and tdoc they earned my trust and I have been able to open up to them. We innately understand our boundaries so we know what is acceptable and what isn't.
