It depends on what symptoms you are trying to treat. If you are trying to focus more on ridding yourself of the physical manifestations of anxiety, beta blockers are probably the way to go or benzos. A lot of people on here have had a lot of luck with adderall or benzos like klonopin and xanax, however, it's real hard to find doctors that are willing to prescribe it and prescribe it in doses that help. Everything you've tried so far has been an SSRI, so you probably want to get away from that and try other classes. You've got SNRI's like effexor, TCA's like elavil, and many drugs that aren't approved for social anxiety but may help you depending on the person like gabapentin, welbutrin, lamital, tramadol, mirapex, ect.
