Condolences on your loss, mate. RIP. I hope you can take a small measure of comfort in the fact that your Dad had a "good innings." I lost my Dad far too soon, at 57, and I know how painful it is, but cherish the memories and your Dad will always be with you.
I'm so sorry, old mate. You and your family have certainly been going through a bad period. Sincere condolences to you and yours from me and mine.
