The thing about feeling you have to achieve something big to get your parents to show approval - maybe, even if you did, they still wouldn't? Maybe it is an unatainable goal? And anyway why should you have to bust a gut just to please them? Would you (anyone who feels this drive) feel relief if you took the pressure off yourself and said "I feel I am ok as I am, and I don't care what you think!" Why should you care what a 'failure' thinks? - because parents are failures if they have failed to teach their children to have any self esteem unless they achieve something bigger and bigger. Wouldn't you feel like a failure if you did this to your children?
Nabster, I never fought back with some people as well and I used to be disgusted with myself for this, but not so much now. I agree with what Smithfield said - that it is the perpetrator/s' responsibility not to abuse someone, not the victim's responsibility to stop them. If they targetted us because we were more vulnerable than the average child - I bet that vulnerability was our parents' fault anyway for failing to bring us up with self esteem and self confidence and to value ourselves enough to not accept bad treatment so easily.
Have you heard of "Fight, Flight or Freeze"? - primitive instincts that kick in, in an intense situation, and in our case it sounds like our body/mind chose to freeze. I think it is partly the primitive instinct and partly the shock that someone who is not supposed to do a certain thing, did it. How is a child with limited life experience supposed to know what to do for the best in this situation they never expected to find themselves in because they trusted the people around them? I think part of it was also just not knowing what we were supposed to do in that situation. In my case it was also my mum's wish for me to "don't cause a scene" and keep everything looking normal and respectable. Emotional outbursts felt forbidden in our house.
I've been thinking about what people have been saying about being in roles in families and then choosing to refuse to take their role as the one being mistreated anymore. I've got a little situation where I used to be in a role with a group of people, a role to make one of them feel better about herself by finding little ways to prove she was better than me. I'm thinking "I'm not going to play that game anymore". Either by not being there, or if I'm brave, being there but not reacting to anything, not caring what people think. I just don't know if I have the strength not to care and not to react. I'd quite like to be there and prove myself ('show her') that she can't do it anymore however hard she tries.
I think the key to some things is definitely to get yourself into a frame of mind where you truly don't care what certain people think of you.
