I'd listen to the docs and then go from there, not necessarily following exactly what they say since they don't know all and probably are not fooling around with attaching motors to bicycles.
I'm a lightning survivor and was required by my insurer at the time (some years back) to see a neurologist. There was no treatment for the aftermath nerve damage and eventual Guillane Barre Syndrome (like polio), but was advised to take it easy, avoid strong exercise and was prescribed medications (pills) for feeling down about loss of a job, a marriage falling apart, being pretty much crippled. So his answer was to sit down and take some pills to make me more or less a vegetable.
No thanks. I believe we are in the end our own best doctors. Sometimes we hire an expert for specialized advice, but in the end our healing is our own path to walk as we see fit. I wanted to live by myself in the woods so that's what I did. It meant hauling water pumped from a well, cutting and splitting my firewood, living in an old trailer in northern Minnesota where it is below zero a good bit of the time in the winter. That said, I tried to be moderate in what I did, knowing I'm getting up in years, but also knowing that we all die... it is a matter of when where and how. I wanted to go out on my own terms. Did a big giveaway, said some goodbyes and went about my life. Got a great little dog who has been a real friend and kept up my human friendships as well. Divorced my thrid X on good terms. Practiced walking until I got pretty good at it to the point of no cane, no walking stick except on icy ground. Tried riding a bike, but had no real leg power, but my balance was good so I looked into some kind of motor I could put on a bike... remembering ads I had seen in magazines as a kid (Bumbelbee, Whizzer, etc.)
Got a motor, started tinkering. Got another motor. It helped pass time through a long winter. Got a China girl and then another one. Found this forum and made a lot of friends while learning all kinds of stuff.
The years have gone by and someday I'll have to do another give away of motorbikes this time. I'm still walking and swimming, putting up my firewood and riding motorbikes. Never did get that prescription filled for pills from the doctor. And I'm glad I didn't. Glad I stopped feeling sorry for myself and got off my ass trying to walk or I think I'd have ended up in a wheelchair. Glad I listened to myself and trusted in messages from Spirit.
Glad to hear you made it past the shadow of death... not time yet. Plenty of time yet for living, enjoying your life on your terms. Be sensible, but so long as you're alive you might as well be living a life if you follow my meaning. We're not done yet, Bud! Woohoo!
