If you can, get some Rescue Remedy from the health food store. It really helped me after my car crash in November. It will take time for the trauma to diminish... if I remember correctly, you are Catholic, so you could also try praying a rosary before bed, or repeating the Lord's Prayer, or whichever prayer seems most comforting to you.
