I also had my first flare-up in years with the pandemic, it was bad enough that, combined with world events, I sort of lost hope and flipped the table.
We moved to a new country in the tropics, a medical tourism destination with good support systems and schools. To be honest, I assumed it would be a place I could more easily afford long-term care and where our savings would go further after I couldn't work anymore - I was in a pretty bad place. I did keep my job remotely after a brief sabbatical, which was great.
It was a dramatic change for all of us, but since the move everything has been... pretty great. I don't know what changed; maybe it's the sun, the change in diet, the new clinic, or maybe (probably) the huge reduction in stress and all of the above. Maybe just random chance. But I'm physically active, I'm more productive than I've been in a decade (my short-term memory is shot and my long-term is fuzzy, but I make a lot of lists and notes), and I'm optimistic for the first time in forever. I had no idea how much stress and fear I was carrying before, not until it started to release.
I'm not saying you should drop everything and move South, but I am saying things _can_ get better. But even if they don't, now is a time you get to make choices about the rest of your life. You may find, as I did, that by choosing your life you also choose to live. We're all just making the most of what we have, some have less and some have more, what defines us is our attitude.
(edit: that sounds a bit overly optimistic as I read it now. I should be clear that I don't have a miracle cure, I haven't fully recovered from my last episode, and I know there are challenges and more degradation on the horizon. I'm just in a much better headspace and environment now, and a lot of that came from taking control of my life.)
