I'm so glad I could help lessen some of your anxiety. One of the things I found when caring for my mom years ago and then my aunt a few years ago was to network network network. Talk until you are blue in the face to find assistance not only for David but for yourself as well. Somebody always knows someone who............yadda yadda yadda LOL. I've seen many folks who couldn't find assistance that they needed and found a way to make it happen by pulling like minded people together and talking to their senators/congressmen/state and locals and letting them know there is a real need. Sing it loud.....talk to newspaper reporters if need be to get community involvement.....I've seen it work wonders! Don't know if you will ever need or want to go that far, but it is amazing what one person can accomplish when there is a need for something specialized

All my best to you!
