Genuine-- I am so sorry about what you went through!
I read this whole thread and have been pondering Sela's idea of free will. I think that, if we are parented in a certain (bad) way that we always will bear the brunt of it in some way or another. It's just too hard to have free will that early in life. Like Daylily, I responded to overcriticism by overachieving. It wasn't until about 10 years ago that it suddenly hit me that I was really confused about something-- I actually thought if I was in fact good on lots of "objective" dimensions that the criticism would stop! I even said to them that I didn't understand why they belittled every little thing I said when, objectively, I was living my life really well and so it was impossible that I was utterly confused, wrong-headed, and unintelligent, so why keep criticising me? Those of you with parents like mine must be laughing right now-- ! The truth is, the more I achieved the more they critisized me because the more threatened they felt. They still do it, although I have a little more control over it, but their first instinct is to tell me I am wrong about everything. I have learned just not to listen, to put my mind on hold when they do it.
I also agree with many others that you have that frigging voice in your head criticising for the rest of your life. I have learned to live with it, often tell it to please shut up, sometimes mock it, and sometimes listen to it for a minute before realizing what is going on. Sometimes I tell it "well, I hope you can get over it!" in a friendly voice. But that darned voice is mine, a legacy of my childhood. Therapy at least helped me realize it is not my voice and that I don't have to listen to it.
