I need some serious help.?

my friend was d by a stupid jerk of her college. he was always flirting with her but she never liked him. when she didn't give him a proper response, he kidnapped her and d her. she returned home after 2 days and 3 nights and he continuously d her all this time. she really tried to resist but nothing helped her. he got more aggressive and harsh with her. he said it was better if you would had listened to me, i didn't have to force you then but you are a nut head, you never understood how desperately i wanted you, now are you happy being forced and d like this, how does it feel? you like it? and he kept raping her while saying all this and like this he kept terrorizing her physically and mentally. now that when she has returned she is still so scared and terrified. she was also physically hurt. we took her to the doctor and she got better physically but she is still mentally so disturbed. she doesn't talk like before. remains silent with sad eyes. her eyes don't sparkle anymore. she used to be so jolly. everything is changed now. she often gets flashbacks and she goes so scared and pale. she feels like the is once again happening to her and she acts and struggles often like it is actually happening again. she also can't sleep properly, have nightmares about the . she tried counseling for a while but it didn't seem to help her much so she left it. sometimes when i am around, she feels better. she has shared the things with me that she hasn't shared with anyone else. and she feels comfortable when i am around. i also try to spend as much time with her as i can. i know she confides in me. i make her feel better. i love her a lot. and the thing that bothers me that even after i try my best and she also feels better when i'm around but still in spite of all my efforts and support she still hasn't recovered completely. she still gets flasbacks and nightmares and becomes hell scared. she cries and begs for him to stop, to not do this to her, to not hurt her, to let her go, in short she exactly behave like all that is happening to her again. i then comfort her, took her in my arms and tell her that it's not being done again, that she is safe now. she realizes that after a while and tries to compose herself then. i can't see her like this. it hurts to see such a dear friend in this condition. i wanted to ask u guys for some suggestions that anything more i can do to help her and make her feel better. i want to see her happy and lively again like before. so plz kindly suggest me something.
