I have social anxiety OP. I have since childhood. I did some mythic raiding in Antorus, barely had to speak. I’ve done high keys and KSM in the past with no comms. The key is finding a guild who accepts what you want/need.
I’ve become better recently, but it takes me a bit of getting to know the people before I actually speak in VC.
Unfortunately my other disability, being partially blind, has made me more reliant on VC.
I despise people who just say get over it. I would “just get over” all my issues if I could snap my fingers and it be done. I don’t do keys this xpac or I’d offer to run with you OP.
Just go at your own pace and find a guild that is accommodating! You got this, don’t listen to the naysayers
