I think what can be learned from this is that your therapist is not your parents. Although the feeling stirred up from your interactions with your parents may be similar, the situation is totally different and doesn't really apply to your therapist intent or motivation.

Make no mistake, these feelings should be explored as the way you experience your therapists actions are valid, but perhaps based on old reactions that can be re-thought, challenged or controlled.

Yeah, it hurts as we confront old patterns of thought, which for some reason we have become really comfotable with.

But sometimes, at least for me, facing that pain head on and trying to change it, is worth it.
