Some people & utube videos for social anxiety cases say that even after 2 years of physiologist therapy there is no result is that true?

Social anxiety: I don't know who's telling you what or which videos you've watched, but social anxiety is treatable. Therapy and medication, alone or combined, are effective. See: http://www.mayoclinic.org/diseases-conditions/social-anxiety-disorder/basics/definition/CON-20032524 and http://www.nhs.uk/conditions/social-anxiety/Pages/Social-anxiety.aspx Hope this helps. Best wishes.
