I was treated pretty badly too, but mainly by my older brothers, and it went on right into young adulthood. My parents tolerated it, especially my mother. The ring leader my oldest brother is a shining example of "Christ like love" because after being a complete jerk to his younger brothers and as they say "crap rolls downhill" so his younger brothers followed in his footsteps, me being the second from the youngest, but then he carried on the abuse to his own children who are now ExJW's and "his children were used by Satan against him". His reward, appointed Elder. I mean after all, his kids are no longer in his household.
So I know all too well what you mean, you carry that crap the rest of your life. I'll send you a PM and tell you more....misery loves company after all...LOL. No we need each other and sharing these experiences are like therapy!
