So sorry you are having to face such an issue. A lot of good advice here, always a good community.
I went 10 weeks combined. Up until diagnosis I was a runner (4-6 marathons a year) and a frequent white water rafter, also gigging most weekends. Everyone, including myself, were so sure I'd just push through it. And I tried. By week 4 all I wanted to do was sprawl on the couch and sleep. I kept trying to push, afraid I'd be letting my wife, friends, and bands down. Soon after everything stopped. I stopped gigging, stopped even playing at home, stopped woodworking. Eventualy stopped caring that I had stopped.
The one advice I give to people is simply to admit you are ill right up front, and life is now not normal. Do what you can, but be honest with people when you can't, or simply don't want too. Take care of you, and let others help as they will. It's not weakness - it's survival.
Thanks for sharing .... this whole experience is pretty eye opening. I wish you well in your continued recovery ... I hope every day is better than the last
