Lesions can show up on the brain, spinal cord, both or just one area.
I was a 22 year old college student when I got hit. Mehra sometimes things are rough but after time you will develope a perspective and that helps a lot. Having computer and internet access will also help you out a lot. I am no longer isolated thanks to the computer. I have friends all over the world and that makes such a big difference.
Try to develope some interests and join on line groups in those areas. You will not believe what a difference that makes to the quality of your life.
