What is the basis for termination? The legitimate reasons to terminate working with a client, as I see it, are 1) the therapist has to relocate, 2) the client is moving out of state, 3) the therapist no longer feels competent enough to proceed with the work, 4) there was an understanding and an agreement in the beginning that therapy would have a specific limited time frame, 5) the client is unable to pay the therapist's fees and the therapist wants to transition them to a lower cost place or practitioner. If termination doesn't happen for any of the above reasons it may constitute client abandonment which is unethical.

That aside, it looks like you don't feel comfortable with her already, not comfortable enough for the 6 months that you have left to be effective. In this case, why not just make a clean break and start working with a new therapist from a clean place where you won't be ashamed or afraid to say that you are being terminated because this will no longer be the case?
