Have you suffered from from social anxiety? If yes, how did you cope with it ?

I have and still do.

I used self deprecating humour to cope.

"I hugged that girl I didn't know, lol"

I wait for questions like this so I can assess my progress.

Weed. Vape pen. Currently have a flavor called frooty pebblez

Nah.

find a job where you don't have to interact much

Yes.
Therapy, medication, and a fuckton of work on myself, and practicing self-compassion.
