NB, I sure hope for your sake that you don't have Multiple Sclerosis. I was diagnosed myself about two years ago when my youngest son was six months old. Of course, these days you are better off getting that diagnosis than you would be say 10 years ago. The disease modifying medications are not much fun, but there are tons fewer people who lose their ability to walk, etc.
There are a lot worse things you can be diagnosed with. I like to call it my "suffering in silence" disease because I don't "look sick" even though I don't feel well. I consider that in itself to be a blessing in disguise. I think it would be harder to handle if it was something that was outwardly obvious to other people.
Anyway, I just wanted to say good luck and to let you know that if you get that diagnosis, it is not the end of the world. It is manageable. I also wanted to let you know that you are not alone!
