Thank you, Sue. Yes, this is a very good overview and very helpful as a start. Then there are all the myriad of individual and sometimes quirkey questions that we have. Those seem to be best answered on sites like these. This site has honestly provided so much guidance and, like so many others on the site, it has kept me from feeling so isolated. Only people who are afflicted with this have a full understanding of the range of emotions and concerns, questions, and issues that arise.
