Type 1 and MS

I am a type 1 diabetic on the insulin pump , A1C-6.5 for the last 9 months. In 1996 I also found out that I have Multiple Sclerosis and taking copaxone. I have been unable to find a % of how many people are diabetic and also have MS. I have been diabetic since I was 3 years old.  I am unable to work full time due to MS. I live alone and on Medacare. Exercise is tough but am able to walk my dog 3 x a day. All my Dr. don't know the % of people that have both. Any help would be appricated and I would like to chat with any one who has both.
