environment changes are a must. What is causing the anxiety? I was put on something similar while I was in an abusive marriage, finally escaped that and within a couple years (divorce was a horrible process as well) I was able to get off of anti-depressants and nerve pills. Doctors would rather medicate than find the underlying issues, just as they ignore our parasitic problems. It is hard to get off of something when the brain says you need it, that is for sure. Your friend must find what would work best for them, whether it be prayer, meditation, exercise, etc. but nothing will work until whatever it is that triggers them so much is gone...
