Be very aware that people are going to say all kinds of things to you. Educate yourself and disregard all those people who "know somebody with MS" or whatever. I've had some whoppers said to me and I know exactly how those comments can bring you down. Take one day at a time and enjoy the baby. These precious baby years will go by so fast!!!
My brother in law has had MS for 22 years and is still working and feeling good. Hind sight is 20/20 so we can now say he has a mild form of the disease. Only many years from now will you be able to say how MS affected you and only you.
