wow...you did and still do have allot on your plate. I am sorry that you are going through all of this and wish I was closer...I would go get your racks for you!! What you did with your Mom and now your Uncle is one of the hardest things to go through...and no..there is no option but to go through it. I understand as we were there with my Aunt and my Step Father. Please remember to take time for yourself...maybe a 1 hour spa. I know it might seem you don't have time to fit it in....but make the time for a massage or something. It really does do wonders.
Not sure of your living situation or that of your Uncles....but might it be easier to either move him in with you or to find him an assissted living apartment. Not a full time hospital type of thing....the ones where they have actual apartments...and someone comes in and cleans for them...cooks for them..etc. It is still a private home that they keep up. ?? Just an idea.
All in all I wish you well and hope that you will take a little time for yourself.
