I'm very sorry for your loss.

I never experienced first hand of a loved one suffering & passing on. I have see ones I care for go what you went through. I watched my old boss for 3 years fall apart with her husband suffering with MS. She just wanted it to end & for him to be free at last. The poor man had it for 10yrs & the last 3 were the worst.

My aunt has MS & the Dr.s are baffled (she should have been in a wheel chair 15yrs ago). She going on 20yrs on having MS & still walking (looks like shes drunk, but she wont stop).

My childhood friend suffered from 8 cancers. It happened very suddenly & 2yrs later he had enough & refused all treatment & passed away 2 days later.

I'm sorry your siser had MS, but at the sametime its good her suffering was over so quickly & it happened with loving family members, you can't ask for a better way to go
*hugs to you & your family*
