Are these behaviors/ feelings... normal?Anything I could do?

For a long time my gf has been acting very lethargic, weird (changes from happy?, calm, sad moods quickly), and had no attention span. Grades are usually much better. Just recently she had some fainting, breathing, rapid heart beat problems (not sure if this has to do with anything). Today she confessed there was someone stalking her who did stuff to her, beaten, forced her into some things, etc her for the past 2 years (I was completely unaware of this. only knew she was acting strangely but thought maybe she just had many bad days or was frustrated at me).... That guy got a restraining order 2 months ago for 5 years. Even though 2 months has been a long time she told me she still feels very unclean or something?, shameful, guilty, angry, sad, all sorts of mixed emotions?, gets nightmares, scared and wants to forget everything. She said she forgot some of it..... but any ways to forget all of it? Should I let it go and wait for time to heal her or are there some other suggestions? Thanks...
