I have extreme social anxiety and my son does as well. Some small tips I’ve learned without medicating:
1. No caffine
2. Eat a good meal before a social meeting or event. Something with carbs and good fats.
3. Learn to do things at off times. (Ex do your shopping really early or after 8pm, same w appointments and other things whenever possible)
4. Take an uber if driving is too hard
5. Keep social situations small. If you have to go to a function if you can, bring a friend to be your anchor or find someone there to stay next to.
6. Read the book “The power of now” by Eckhart Tolle
7. Write about it. Read about it.
8. Get a good night sleep. Schedule it if you have to.
9.Be kind to yourself. Lots of people suffer from this and learn how to live and deal with it.
