My cousin once removed has MS. She lives with it, but it does tend to dominate her life rather like if someone ends up with gradually increasing visual problems. Because it is an incredibly physical world and is not set up to accommodate people seamlessly as they have problems that periodically shut down some part of their physical body. That said she has had a full life with all the ups and downs, marriage, children, etc.

Not all problems can be solved, but all problems can be managed.
