social anxiety/ panic disorder

Hi, I am a 54year old women with a social anxiety panic disorder. It started in my 30's then I had it in control and got off meds but in my late 40's it was back with avengence. I have been taking Lexipro 20 mg. for about 7 years before I thought I didn't think it was helping me so I asked my doctor to switch me to zoloft hearing from others how it helped them. Zoloft did not help so my doctor switched me to prozac 20 mg. since that's what helped me in my 30's. Well it's been about 1 yr on the prozac and social situations and going on trips away from home have become unbearable. I just want to come home, I get all nervous, lose appetite, and just want to flee. I just feel like I can't live my life. My husband has been so supportive and says everyone has bad days but the rest of the days I am OK, it's just when a social event or a family trip happen I can't cope. My doctor suggested taking Xanax when the feeling escalates but than just makes me sleepy. What other things can I possibly do so I can try to enjoy my life? Please set me know?
