So sorry anon, must be devastating news. Have known several people with MS over the years, including my sister. The course can vary a lot; my college advisor had MS and is still teaching after over 20 years. My sister was mobile for about the same period although finally needing a wheelchair and assistance to do things.
Much more research is being done now than in earlier decades. And there are more treatment options available than before. Our prayers go out to you and your family, anon. WRWY.
