I've Been Depressed And Have Anxiety For 15 Months. I've

I've been depressed and have anxiety for 15 months. I've tried several anti depressants and am currently on 200mg of Zoloft and .5mg of risperdal. But I still have symptoms. I've been on Zoloft for 12 weeks. It has helped me, but not enough. I am also in therapy. Not sure what to do anymore. I've tried Effexor, remeron and Prozac.
