Walking away can be seen as a good and healthy thing to do for yourself, but it can also be a very typical borderline reaction too. Are you sure that you are not reacting to your T setting limits that you do not like? How will you feel when your next therapist sets limits that you do not like? And are you sure that what you see as inconsistency isn't just you judging her behavior as either good or bad based on how you feel about it? That could look like she is inconsistent when she doesn't always give you what you want or expect.
