Seconded. Bobiverse is great to listen to while mowing the lawn or doing other mindless jobs.

Maybe offer to shout them a nice dinner once a month. I know it involves money but it’s more of a gift than paying their bills.

I don’t know about illusory hearing as related to RSD but I do know that I had similar issues most of my life.

I used to think people were looking at me, talking about me and sometimes thought that they could hear/guess my thoughts. Started when I was a kid. Found out it was ASD-1 and a brain tumor causing alot of the issues.

And the only way I found out about that was by going to the doctor. I really do recommend speaking to a doctor about these issues and you might be surprised with what they find and how much better you feel once you can get the right therapy.

If you are neurodivergent, it might be worth looking into Rejection sensitive dysphoria and Social phobia.

It may feel like others are judging/bad talking you but that may not be the case.

Speak to a GP or psychologist, they can help with these types of issues.
