My 17 yr. old girlfriend got raped this week; how do I comfort her (I'm 17 too)?

I know I already asked this question but I wanted to add details. She was brutally raped this week and just got out of the hospital. She is traumatized and has panic attacks. I don't want to overly comforting but I want her to know that I love her and I never will leave her. I also wanted to know if you think this would be a good idea: When she has panic attacks I cuddle her and whisper sweet things to her and it works so I was thinking maybe if I could cuddle with her in my bed until she feel asleep and then I could get down and sleep on the floor and then If she has a panic attack I could help. Thanks.
