I Have Severe Anxiety And Have Tried Prozac Effexor Which

I have severe anxiety and have tried Prozac Effexor which worked in past, but made my anxiety worse. Was going to try Zoloft next, should I give it more time if anxiety worsens and hope that eventually it will work?
Tried kionopin which works only for few hours before it is back again, don't want to take bentos everyday
