Sorry about your health. I hope the new wheelchair helps you get around better and other health remedies have desired effect.
I never really knew there was a Bitcoin community on Facebook, I don't use the app much anymore though, so I'm not a good information source. Bitcoin is easy to understand and use when you have the right resource material and use the learning channel that gives you the best results.
I couldn't find the channel you recommended, would you mind sharing the actual account name. I enjoy finding good Bitcoin content especially on YouTube.
Just type it in the search box and you'll probably hit one. In my country it's a generalized one a Filipino crypto community so it's not just bitcoin but also other crypto out there, it's rife with scammers though I think a natural thing in Facebook groups so if you plan to check them out, tread carefully as there's people out there that don't want to fight fair.
Cheers to you OP, hope that you're going to recovery sooner than you'd expect and at the meantime take care of yourself as much as possible.
