opiates for anxiety only thing that works?

I have had pretty severe social anxiety disorder all of my life, bad enough to see a doctor about it. I was prescribed lexapro(SSRI) but it didn't do anything for me. Benzo's knock me out and the only thing that seems to work is oxycodone(percocets not oxycontins) I know this is unrealistic in the long term and carries an extremely high risk of addiction. Any suggestions?
