Yes, I agree with spikes. If a therapist or pdoc thinks they cannot help you or that you're "too much to handle," they will say it. Sometimes they'll say it on their own, or sometimes you'll have to ask.

If they genuinely wanted to get rid of you, they would do what my first therapist did: call me a liar and a manipulator for telling my pdoc that I was depressed ("you're not depressed. You've never experienced it before, so how would you know? You need to tell people the truth!"), and she then after she got sick of my "lies," she deleted my appt and gave it to someone else, then put a request for me to be internally transferred to someone else, all without telling me. (I'm actually going to report her later this week to my current therapist.)

Most therapists are not the slimy vindictive type though. Such therapists are a rare breed of filth. But even though she was a POS towards me, she at least did transfer me to someone else rather than cut me off entirely from the practice (maybe because she didn't want to get caught?). So, I think that even if it got to the point where your therapist was legitimately "disgusted" with you, she would at least transfer you to someone else in the same office (if you do go to a practice w/ multiple therapists) or tell you that they can't work with you anymore. They'd get in big trouble if they didn't do one of those two things.
