Brack .. really feel for you mate , know exactly what your goin through .. Hadnt really got on with my dad for 15+ years , but last year he was admitted to hospital with bowel cancer and the 8 weeks he was in hospital , i spent as much time with him as i could and we talked , which is something we had never done before, we managed to build a few bridges and patch things up , just before he died ….
Thing is , he died exactly 1 year ago today !! .. 7.31pm to be precise ..
I know it may be hard , but you really need to sort things out, even if its just for your own peace of mind …
Hope you sort it and good luck
