I am sorry to hear of your mother's passing. My mom was diagnosed in 1997 and then I was finally diagnosed in 2003 after an initial diagnosis of sjogren's syndrome and migratory arthritis..... It's tough sometimes but fortunately god has kept a hedge of protection around me and my mom.
Don't get me wrong we have had some hard times, battling blood clots, kidney disease, joint pains, fainting spells, fluid on the knee (numerous times).... The list goes on and on between us.
I just wanted you to know that I sympathize with you because everyday I dread the fact that I could get a phone call saying that mom had taken a terrible turn for the worst and that she could be snatched away from me in a blink of an eye! I just pray because I am a witness that prayer and faith can truly protect and keep you when you know who jesus is and the promises that god has made to each and every one of us!!!
