Welcome to ThisIsMS, Juley. I am so glad you decided to join us. With the MS diagnosis so recent as September, 2012, you have so very much "newness" to deal with! You say, "I've always been a strong, competent and capable person who never let anyone down." I see no sign that you are letting anyone down NOW. In fact, I'm sure you are still strong, I'm sure you have passed that trait on to your twins. In addition, you are giving your husband and children the chance to learn compassion, understanding of another's situation and feelings – your children will have a kindness, a thoughtfulness, and an unselfishness that many others lack.
MS is a major challenge; you are handling things quite well (as I see it); you cannot change the behavior of some people – they will never understand – they will always have thoughtless comments. This MS experience will sift out your sincere friends and family; energy is dear when one has MS – don't waste your energy in trying to educate those who don't want to learn.
I also welcome Chris, who is so very eloquent in stating what many of us here feel. Your girls must have learned so much from you – the same kindness and empathy that Juley's twins are learning now from her. This community at ThisIsMS will benefit greatly by having BOTH Chris and Juley here!
My hypothesis: excess insulin (hyperinsulinemia) plays a major role in MS, as developed in my initial post: http://www.thisisms.com/forum/general-discussion-f1/topic1878.html "Insulin – Could This Be the Key?"
