The reason she hears voices, has increased suicidal ideation, etc etc, is because of the medication. Doctors are idiots... sorry to say, but they are. They get a person, give them medication, then forget about the side effects the medication causes to people uniquely. These very side effects are common from medications given to any person with PTSD. Take away the medications, you then have withdrawals which makes a person worst again for a couple of months, to suddenly have lesser symptomatic issues. Funny that!!!
