I'm so sorry to hear of your loss Sally. I hope you have got someone there who can be strong for you as I know you are trying to be so strong for everyone else.
MY heart goes out to you and your family. So sad for you all but as has been said before at least your uncle's suffering did not go on for a long time. Try to cling to that.
