Thanks for the vote of confidence @Rebecca!
I'm sorry to hear about the medical emergency but it's great to see you back and ready to pursue your goals. As a previous Super Host, you already have a strong foundation to build upon. The only snag I see is that the Feb 2020 review is the first everyone will read, but it is outshined by all the other glowing reviews. You were obviously doing all the right things.
Three suggestions immediately come to mind:
(1) If you are willing, you might consider sharing the reason for the gap in hosting. What you wrote above is perfect. It's no one's business, but some potential guests may wonder why the gaps exists and addressing it - at least for a bit - might help assuage their concerns.
(2) Take a look at all the updates in the hosting platform. Some things have changed or been moved around in 3 years. For example, Instant Booking is now available to guests who have no bad reviews. You might recall that it was available to guests who had good reviews. That's a big practical difference.
(3) If you can and have not, publicly respond to your guests' reviews. Say thanks and note if anything has changed. Did a restaurant not make it through covid? Did you purchase new mattresses? You can use the guest reviews to highlight those changes. But, be sure to also update your description.
Please know that we're all here to support you every step of the way. Could you share some specifics that you'd like feedback on? I'm sure with some collective advice, and your own know-how, we can help you get everything back on track.
