I am sixty-one years of age, was dxd with MS in 2003, but I have had symptoms for thirty years. According to the neuro, my MS is mild. I will continue to live my life as I did prior to my diagnosis - enjoying the moment and not living the future. Maybe I would have a different outlook if I had experienced a major exacerbation - but, I'm not going to spend precious time thinking about "what if's".
Enjoy where you are for today - tomorrow you will have new things to work on whether you have MS or not. I agree with a previous post - go to the beach, enjoy a sunset with your wife (or a sunrise
); be thankful for what you can accomplish.
