I'm sorry that you were triggered by that movie. I would be too if I Saw it and I didn't have to deal with childhood abuse...but for me those types of things will make me nervous, scared.
I get alot of body memories regarding that kind of thing and it is scary. I at times had to hide my face during a scene because it bothered me so much. The movie Trapped bothered me like that and I bought it!!! Why, not sure.
Memories can be tough to deal with but the more you talk about it the more you learn to cope with it the easier it does get.
Sometimes memories will just surface, even if you do not recall it. It could be the littlest thing. But if you are having that fear and feel sort of connected to that actress then perhaps something did occur and you blocked it out.
But it may not have, just the propersition from your cousin could be enough to make you remember that etc.
Therapy will help you to deal with this kind of thing, and maybe you will find something that you don't want to know, but at least then if it is true and there is something bothering you from the past you have someone to talk too.
