I went down to using a walker and was thinking wheelchair. At about 2 yrs out mt legs started getting stronger(my b-12 was on the floor to start) now I can walk free but not over 200 yards or so at a time. I hope you are not drinking Alcohol and I hope you know what your b-12 number is. That b-12 is not a "thing" my number went from 119 to 900+ and my legs got stronger. They are not still getting better as there has been no more improvement for 6 to 8 months now. The panic of newcomers and the sense of loss associated with this condition both drive some people to thoughts of suicide. Most usually just get really pi%^*(d off. Fine tume their diets and get as much exercize as they can tolerate. Your symptoms will change with time so don't feel that anything is permanent. I cannot do the job I did for all my life, get paid for my experience because I cannot climb oil production tanks anymore. I have since trained to be a dispatcher at one of those shale fracturing outfits. So yea there are jobs out there that may be different but change is always hard. If you can look around and count a blessing I feel that yes indeed God will help you. Good Luck, Ken in Texas.
