My wife was diagnosed with RRMS (relapse-remitting) around 5 years ago. She works as a recreation manager in a busy community coordinating ongoing activities and planning large events. Since her diagnosis and the process of acceptance for both of us, we've had two children, both finished, (or are finishing), school and generally lived our lives to the fullest. Sure, there are and always will be limitations, but I've learned to enjoy our life together within the limitations. She keeps in regular contact with her neurologist and we try to maintain a healthy diet along with regular exercise. Believe me, I know this is hard and scary right now, but there is hope. If you are diagnosed with MS, there are many treatment options available and support groups to help you understand the disease.
Remember, one of the best treatments for any condition is a positive attitude. Prior to my wife's definitive diagnosis our options were MS or possibly a tumor....we were glad to get the MS dx. Try your best to have faith, (whatever your faith may be), and remember to count your blessings. You'll be in our prayers.
