Hi, there! I face similar problems. I can do well if I'm talking to just one person. More than one is too draining and awkward for all involved. Sometimes I can't even hold an online chat that involves 3 or more people.

I freelance as an academic editor. I work either from my apartment or a nearby library. I find the job easier since it doesn't require face-to-face communication. Plus, the fact that communication is necessary for this job makes it easier. I have no choice other than to join in on video calls or project meetings. I turn off the video all the time, though.

I only say this because if your job involves email or telephone support more than face-to-face, in-person support, it might be easier than you think!

Since it's more than a month since the original post, I hope your job's going well
