I can't answer from a CALS perspective, but will do so from a PALS perspective.
To start with, I am a very private person. Much more so than most folks.
At first I was very, very reserved. I told my wife, my pastor, my close family members, and my business partners, in that order, over a period of weeks.
I pretty much tried to hide it from others.
I did gradually start opening up to others.
When I stopped working (shortly after diagnosis), I told those that I had worked with a bit about what was going on. When I started using a wheelchair, I started telling more folks.
Now, I tell anyone that inquires. I have realized that I have nothing to hide. Sharing with others provides an opportunity for them to help in small and large ways.
I do everything I can and post stories about my adventures. Well-meaning folks have cautioned me that I should not do so because they fear an insurance company could suspect I am not disabled. Right. I think even the slightest of investigation would reveal that I am truly disabled
. One of my goals is to be the most positive influence on others that I can and sharing my adventures is a big part of that (in my mind).
My friends and family have not left me. In fact, many of those relationships have grown deeper and richer. I know that I am blessed in this regard. Others here have reported that even seemingly good friends and family have responded to the news by backing out of the picture.
