just wanted to say thank you to everyone who offered their insight and support when i asked questions on the forum over the past few weeks, sadly my wonderful father passed away last tuesday and i still cant believe he has gone. there were many things that we as a family learned along the way so i hope i can be of some help to others on this long and painful journey, there were some things we got wrong and many things we got right but whatever we did was always in the best interests of Dad - he was the planet around which our world revolved and has left a huge gap.
