@cheryl602 , I’m sorry that you have been given this diagnosis to deal with.
What does the future hold? Nobody knows, from the healthiest to the sickest. Life is wildly unpredictable for everybody.
But, it’s natural to have these thoughts, It is part of the grieving process for the life we believe we are leaving behind.
MS is no longer the condition that is talked about in hushed circles. It’s still a taboo subject, which is a shame. It is now a condition which can be managed by medications developed over the last 20-30 years.
So, take your time as you process this diagnosis. Do some research, at your own pace. The “Newly Diagnosed” tag on this page is a good place to start :-
