Sorry but I disagree with your t here. Any trauma can cause amnesia. I understand what she is saying about life and death but think it is a kind of misunderstanding.
I have copied a sample from a webpage on psychogenic amnesia:

It is most commonly associated with traumatic events or violent experiences involving emotional shock, such as being mugged or raped or involved in car crash. Those at increased risk include those sexually or physically abused during childhood, those who have experienced domestic violence, natural disasters, terrorist acts, etc, soldiers who have experienced combat, and essentially anyone who has experienced any sufficiently severe psychological stress, internal conflict or intolerable life situation.

Basically you can get the amnesia because you just couldn't process what was happening to you. You needed to dissociate from what was happening. Also if you had to continue to live with your abuser, amnesia is more likely as you needed to stay in that situation for your survival, meaning you had to dissociate from what was happening. However any kind of trauma can cause amnesia.[/QUOTE]

Thanks for this. Also to add, she seemed to suggest that if I was sexually abused early teenage years then I should remember it. It would only be amnesia from teenage years if I was threaten with death. I guess she is also implying that pre-teen years you can have amnesia with sexual abuse because I guess you're more vulnerable. Thoughts?
