Snowflake,
Karen is right, your mind will protect you and you will be doing the Hypnosis under control circumstances.
Was I afraid of what I would discover about my childhood, no. In fact it was a release to have someone validate what had gone wrong and how I should let go of the feelings of insecurity and be told by my therapist to change my core beliefs as they were inaccurate.
I lost my Mother when I was 18 months old to a car crash. When I was 5 years old my father remarried and I guess you could say I did not have a chance. My step mother's only son had drowned before we came into her life and I feel that she was sadly disappointed as she thought I could replace him. I could not do that and she resented me for being alive when her son was gone.
She also was a drinker so when she got through with me I believed I was just a worthless burden and she wanted me out...................long story.
I learned a lot in therapy. It was not my fault. I was a daughter without a Mother.
Bless you sweetie and I know your afraid but face that fear and go slow.
Hugs
Kitt
