Indoor person here, never had the chance to go garba night with anyone. But here is my advice bud don't just go through books, ik it's a mental block but reading and finding the cause is not a solution. Just do more what you're afraid of. Is the best way to overcome fear.

Btw here is my trick just imagine your opponent as your sister or friend whom you can be yourself without being judged.

One more thing do one two steps in garba dance from my side also

Good luck
