Spend more time with her. I am recovered myself, and I noticed two things; 1) Schizophrenia turned me from an extrovert to a complete introvert 2) Recovery made me go straight back to extroversion
I advise getting her to do less solitary activities (Internet, television, any electronics basically, reading, ect.) and get her around people to engage in conversations with. I think that we do sort of miss our voices as long as they werent all evil, malicious voices (2 of my 3 voices were) and recovery creates a gap that MUST be filled with reality.
Voices can be like having company with you 24/7. So get her around people! I have made new friends and have rekindled old friendships since I recovered. I don’t find myself alone on the weekends hardly ever, seriously. I suggest you have her take the MBTI, Myers Briggs Type Indicator (its short and easy and free and all over the internet) http://www.humanmetrics.com/cgi-win/jtypes2.asp
This test will tell you if she is extroverted or introverted. Keep in mind that the VAST majority of people with schizophrenia are dominantly introverted. If she is introverted, it is a sign that she was comfortable with her voices. If she is extroverted, it means that she will have an easier time filling the gap that the voices have left with real people.
I talk to my friends all the time. I have old friends on FB who I chat with all the time, I see my friends in town on a daily basis, and my weekends are usually filled with socializing, not me being alone like I used to. I have also gotten into powerlifting, and I see the same people working out there all the time and am friendly to them. I made friends with people sitting next to me in class. I hate being alone on the weekends, and usually I hangout with my two of my friends on thursday nights but one’s parents are visiting and the other has to clean his house for a family function, so here I am, on the internet again.
