I experienced emotional and psychological neglect. I always felt that my parents never needed me - that I was just a tenant in their home. My father never even spoke to me just liked his liquor and licking his wounds. My mother to this day is very detached and still doesn't need me. She is remarried now and if I don't call her she never calls me. When I ask her why it is the way it is I just get uncomfortable silence.
I could never go to her for help when I was troubled and when I was in my 20s with plenty of emotional baggage, the first time I asked her help just for advice her reaction was "how could you get yourself into this situation".
Her coldness made me fearful of being a parent. I left it very late so now have a much loved daughter of eight. My only regret is that I did not let go of my fears to get off the pill sooner so I could have had one more child.
There you go - some things just defy explanation and there is a generation of parents who never say the word "sorry" and can never been shown up to be wrong about anything so I don't bother.
