This movie traumatized me ever since...?

I watched Stephan King's, "The Green Mile" about three months ago and ever since, i can't sleep and it's been bugging me. What really scared me was when the guy who befriended the mouse got sent to the electric chair and the evil guy didn't wet the sponge so the guy kept getting electicuted and it smelled and omg.... it was horrible. And my favorite actor, Tom Hanks is haunting my dreams and now i think he's an evil person because he didn't protect all those people who were on death row. And the evil rapist guy who d those two girls and spit moon pie on the officer is in my nightmares and The Green Mile was so disturbing. Not like, "omg, so scary close my eyes ahh" but like, psycologically scary. It really messed with my mind and i'm going crazy over how much it bothers me and i can't stop thinking about the asian guys dead face where his eyeball was all messed up after he got electricuted (that's sounds funny,lol) and how the evil rapist squished the mouse. I cried three times during the movie and i am still bothered by it's strange sick twisted perverseness. does stephan king usually have that effect on people? help, please, what do i do? one, freaky movie SHOULDN'T make me freaked out for two months. I mean, it's not constant. But every once in a while (like every three days or so) i get reminded of it and can't sleep and all day at school i think about the poor people on death row and the electric chair and OMG scary Tom Hanks and then him in Apollo 13 and his bladder problem in the green mile and it freaks me out. What do i do?
