That was tough to read! 15 years ago I was in a coma for 6 weeks with pneumonia, when I came round I couldn't even stand up. I was only 20 years old, a fit athlete, rock climbing 3 or 4 days a week. Took me 6 months to recover, and it was one of the hardest times of my life. I thought I was going to die. I never recovered my full lung capacity, but I only lost an estimated 10~15% according to doctors.
Hope you come round tbone, it sure is a struggle mate, but I'm sending my thoughts out to you and yours
