This must be so terrible for you, my grandad dis-owned my father when i was 3, he dies last year of cancer and we didnt even no, he dis - owned him over a tupid signature because they have the same name, my grand mother dis-owned my dad when i was 11, we wer real close up until then and then she took her son in laws side in a stupid arguement over religion, shes now dying of cancer also, i hated them both, sometimes i think if they had of been in my life or my dads life that things could of been so different for me now!! Family are ment to support us no matter what but in reality, family cn be our biggest and worst enemy's... Did u ever have a close bond with ur Grandad? Or do other family memebers have a close bond with him? I no this may sound harsh but ur a better person than him, dont ever let him bring u down or control how u feel, he obviously has demons that he never delt with dont let his demons hunt u, we already have enough of our own... Hugs to u, I hope your ok
