Yes, I think it is important that you like your therapist.
And... I think it is important that your therapist likes you.

I agree with what others have said about how sometimes a person can grow on you even though they rub you up the wrong way initially.

But I also understand that sometimes the fit is simply not there and three sessions (or even one hundred sessions) ain't gonna fix that.

A lot of it does indeed depend on WHY you didn't click with her. I've had some who I didn't return to, and I've had some who I gave a chance over a few more sessions (and some of those worked and some of those didn't).
