I was abused emotionally, mentally & sexually for three years..
I was 19 when it started and as naive as a 7 yr old.
I dealt very poorly with it to be honest. I was in denial, I was an enabler, I pushed it to the back of my mind.
It has changed me - forever. I am frigid, I cannot stand the smell of alcohol on anyone's breath & avoid places like bars & bonfires. I have a phobia about being "cornered" even if accidentally.
It has changed all my relationships. I am too passive. Men got upset because they can't "please" me. My marriage works because good ol' Mr. Ruth also has a low libido (Thank God for matches made in heaven!)
I was old enough that I can remember it if I push it up in my memory. I am sure that I have Post Traumatic Stress Disorder to some degree. If I even suspected that I had been abused in my childhood I would probably strongly consider the regression. The suicidal thoughts would be there BECAUSE the memories were submerged - just not deep enough anymore. If the memories are brought out it would be rough for awhile until it's all sorted out -
but at least you would KNOW what you are - or are not - dealing with.
I know this really didn't address the concept of buried memories that you are asking about. But abuse is so much more common than you know because people don't talk about it. Thought you'd like to know there's someone else standing shoulder to shoulder with you on this one.
