I don't know how to respond to "hope you get well soon". Unless I manage to treat the underlying cause, I will never be "cured".
Many years of trying and failing have allowed me to get "better" at not being nervous around people, but in my case I know that the social anxiety stems from Aspergers.
It is a rare neurological disorder that makes me unable to pick up on certain social cues, and has led to years and years of social paranoia, anxiety and ultimately depression. So unfortunately the only way for me to completely get "rid of" the symptoms would be to announce to everyone I meet that I have it, but that would cause them to not treat me as a normal person, so instead I've opted to suffer (mostly) in silence.
