Sounds like PTSD. I worked with a research company back in 2001 to get venlafaxine FDA approved for treatment of Post-Traumatic Stress Disorder. The numbers came back in favor of Welbutrin, but I still have a lot of faith in effexor.
The reason the numbers came back is that effexor is a very mild dissociative. It puts you outside of yourself. At the same time, it bonds seritonin and dopamine, given an effect that is like MDMA until the body conditions to it. Trauma is something that happened, not something that is happening. No one is ****ing on your shoes right now. No one is raping your girlfriend. But, to deal with the fact that it has happened, it takes a distance between one's momentary essence and one's experience.
I would recommend PhotoReading "The Screwtape Letters" by C.S. Lewis, and activating fully the sections where Screwtape speaks to Wormwood about Time. Now, if I am a Satanist and I'm telling you to read the works of a respected Christian intellectual, there must be something heavy in there, and there is. When you are living in post-trauma, part of your being is still in the past. You're not flowing naturally through time, but instead anchoring yourself to an event in your history.
Since you've posted on the PhotoReading forum, I'm going to give you more encouragement than advice. Isaac Newton said that if he was able to see farther than his peers, it was because he stood on the shoulders of giants. You have the giants of psychology, psychiatry, religion, NLP, etc. available from your library for free, and available from bookstores at modest prices. (Previewing and PhotoReading a book at a bookstore is a good way to know if you'll gain anything from buying it). I'm confident that you can be the archetect of your life. You see, when you build barriers to keep out pain, then those walls are designed by those who hurt you the most.
You will probably not be able to "save" your girlfriend. I've played Messiah for no fewer than four sex-abuse victims. I'm not saying she can't be "saved," but if she can be, then she must be her own Messiah.
Good luck.
