I'm so sorry that you are dealing with this. It sounds awful, I can't even begin to imagine how you must be feeling. I think I would lose my confidence in therapists too, if this kept happening to me.
Still, I agree with Lostislost that these therapists were not the right match for you. Sometimes it takes a while to find someone who is going to not only stick around, but also truly help you. Please don't give up, you deserve to be happy!
This may be a bit of a silly suggestion, but have you thought about trying to find a male therpits? Or an older female one? Of course, there is no guarantee that they won't have things in their lives that will make them unavailable, but maybe it would be good to change the pattern a bit? Just a thought.
