Cathy, I'm sorry that you are lacking the moral support you need from your family. If only any one of us could figure out family dynamics...!
Can I share a more supportive story? A year ago I was dx'ed. Due to the timing of the dx and what was going on at work, everyone in my office found out right away. Other than giving me the time I needed to get myself together, they haven't treated me any differently and since a year ago, we have seldom talked about it. On Monday I found a MS walk brochure in my mailbox. It was being circulated through the office by some of my co-workers who have formed a team and are soliciting additional members. I can't describe how deeply their action has touched me. Often, I wish they didn't know about my MS, but I may change my tune because it has given my co-workers the opportunity to show me how beautiful they are. I wasn't planning to do the walk, but I am now!
