Did the Buddha have advice about dealing with social anxiety? Does anyone know if the Buddha said anything about social anxiety and how to deal with it?

I believe social anxiety is common in our day and age because people are more isolated now, but may not have been as common in the time of the Buddha. So if there is nothing specifically about social anxiety, can you provide info on what the Buddha said about dealing with anxiety (in general)

(Also as a related question: Is anxiety considered a mild form of fear or are they separate in the Buddhist teachings?)

Please provide sources if you can, thanks!
Anxiety from loneliness is overcome with concentration; with developing calmness. 

Anxiety from worries about social conformity is overcome with clearly understanding of right &amp; wrong, i.e. morality. 

The Dhammapada says, for example:


  
  Those who are ashamed of what they should not be ashamed of, and are not ashamed of what they should be ashamed of — upholding false
  views, they go to states of woe.
  Those who see something to fear where there is nothing to fear, and see nothing to fear where there is something to fear — upholding
  false views, they go to states of woe.
  Those who imagine evil where there is none, and do not see evil where it is — upholding false views, they go to states of woe.
  Those who discern the wrong as wrong and the right as right — upholding right views, they go to realms of bliss.
