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.
