Bloody hell mate that is harsh.

If it helps, hold onto your tools, it may feel like the end of the world at the moment but you would be surprised at what cripples can actually achieve when they put their mind to it. I've spent three years of my life being unable to walk without using crutches. Sucks but you do adapt and find ways to do the things you enjoy, if the only way to grow some veggies is to crawl around the garden on your arse, you crawl around the garden on your arse and the veggies taste all the better for the extra work you have to put in.

Things will get better, not the same as before but much, much better than you are feeling now.
