Sure! I will warn everyone now though, that this will likely be a long post, and may be scattered with bits of TMI.

First off, mine is not a "typical" spinal cord injury that resulted from the trauma of a wreck, fall, etc. Mine is called a non-traumatic SCI in that it resulted from illness, specifically an autoimmune disorder called Transverse Myelitis. The super-short explanation for TM is this: if you think about your spinal cord like a computer cable, you've got nerves on the inside and insulation on the outside of those nerves called myelin. Just as a nick in insulation would make your computer cables ineffective, damage to the myelin makes it difficult to impossible to conduct nerve signals. What happens in TM is that the immune system for some unknown reason starts to see the myelin as foreign body (like bacteria or a virus) and attacks it.
How it happened for me was like this: On March 24, 2005, I was at my job as a CNA at our local Children's Hospital. DH worked downstairs in the ER of the same hospital, but my shift that night started at 7pm, he was due to go on shift at 11. About 8pm, as I was checking vital signs on one of my patients (a 15mo boy with sickle cell) both of my legs from the knees down felt numb and tingly, kinda like if you sit on your foot and it falls asleep, only it was as if a switch had flipped. Now I had suffered an attack of this disorder previously in 2001 (but had a full recovery) so I knew immediately what was going on. I called the physician on call with my neurologist's office, who actually offered to come up to the hospital and examine me b/c of of my history, instead of sending me down to the ER. I also called my DH and parents to come up there. Over the next couple hours, the numbness progressed up my body, and my legs began to feel heavy and clumsy. I was admitted to the hospital around 11pm, and around 1am noticed I had wet the bed. They helped me to a bedside commode to finish using the bathroom while they changed the bed, and I almost fell on the floor. My motor function was gone, and I haven't walked unassisted ever since.
With any SCI, the amount of function lost depends on the location. From the top, you have 7 cervical, 12 thoracic, and 5 lumbar vertebrae. The higher the injury, the more function you lose. The damage to my myelin is at the 6th thoracic vertebra, which functionally means paralysis from about the base of my breastbone down. I have weak abdominal and lower back muscles, and am completely dependent on my wheelchair. I do have some movement in my left leg (toes, ankles, knee), but it isn't considered functional movement, meaning that I don't have the strength to stand on that leg or walk. I was able to walk about 60 feet in physical therapy a few years ago, but it required the use of a tall walker and a set of big, fancy, complicated leg braces. It was a good feeling, but it was so much work to hold myself up that it never would have developed into anything functional (at least I doubt it). I quit PT halfway through my pregnancy with my daughter, made peace with living my life in a wheelchair, and have not been back.

So that's my crazy long story of disability. It all started only 5 months into our marriage, but he stuck with me through thick and thin and we celebrated 5 years of marriage last fall, then mourned 5 years of disablity this spring. I get frustrated at times, but try not to let it hold me back too much. I still had my daughter and have been blessed to be a SAHM the last 2 1/2 years, and this fall will be returning to school to attempt to finish my nursing degree.
Oh, and I'd be all for trying to roll the Princess marathon! Unfortunately though the wheelchair use has led to carpal tunnel syndrome. I can usually manage a couple miles to roll around my neighborhood, and am working on stretching that, but I think at that distance my hands would fall off!
He does not get me food that he knows I can not eat and he is relativity supportive in my journey, but it does not phase him to sit down and eat a huge bowl of ice cream or anything else that is super delicious right next to me. 
Luckily I have crazy will power and know that I can not even have a taste or I would not stop and just eat everything. 
It is very supportive and lacks the "clicky" atmosphere that most threads have.

Knowledge is half the journey!!
