For me it would depend on what it was about her that I didn't like. My first few months of therapy were incredibly difficult and I was finding a LOT of things that I didn't like about it. But when I looked at each complaint I realized it was either not that important in the overall process or more often-- that it was just an excuse for me to quit. At this point, I'm glad I stuck it out with my current T.

I would try to figure out what it is you don't like about her before you leave. This way you know what you are NOT looking for when selecting your next T.
