I ask this question to my doctors with each new dx on my MS aside from asking myself and God why and what and when  .... while I have heard of many who repeat the  mantra of this will not defeat me so many lose faith and hope of this ever changing disease.   I may not make too much sense any more , as there was a time I could write up a storm and while I am in the mildest form of MS at 9 yrs. , the disease mutates and changes so sure it is easy to say MS does not kill us but we do not die from the disease but rather "complications" but as I see it it we do die from this disease ..   I am 53 and as I stated 9 yrs. now and finding that even though there are new treatments , new discoveries and new eveidence there is nothing new to answering this question ..   Each case is different, each case is not easy to hear of how a person dies from MS and after hearing most stories and losing a schoolmate from MS I cannot say how or what to expect but rather focus on living out my life with dignity and so I believe that we all know the deal, it just when should we stop fighting and that is when hospice or some other agency that can help you handle and plan a course that fits you best ..   I pray you find that course , I pray you hold onto the thought that you are not alone , you are never alone and that your feelings are justified and that you may never get the right answer here , I pray you can just take time to breathe it all in and remember you are loved ..
