Hi Rosalind! First of all, thank you for being brave enough to put these words out to the world.
I also have a chronical illness but it's a pulmonary one, so I ended up heving to "come out" to people a lot about it because of coronavirus. It was scary at first but the truth is that people don't really have problems with it. They're nice, every time. And I think that is regardless of whatever disease we're talking about. Just an extra comment to make you feel you're not alone :)
