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!
