Pls help me get leg braces to stand up “alone”

When I was 18, I got shot in my left arm and the bullet came out of the right side of my back. The heat of the bullet burned my spinal nerves left me paralyzed from my bra-line down. The doctors said I wouldn’t recover, but it’s almost been two years and I’m healing slowly. I believe that having leg braces would help me heal so much more and not only that, but it would also help my body be more comfortable. I miss standing, I miss walking. Please help me with whatever you can, I’d greatly appreciate it <3
