my father in law had throat cancer.. when they did his biopsy they admitted they split it and couldn't find the other piece.. he went thru chemo for his throat for a month.. today he said he felt like he was dying..squad took him to er... the cancer is in his brain. don't get me wrong he was a dick before and now he's a super mega ass hole because of the chemo and cancer and shit. and this needs to end now. but can I get prayers for this drama to end and for him to go peacefully? he has internal bleeding in 3 places including his brain and his kidneys are failing. and I know it's the doctors job to fix him. and I know it's my husband's dad. but he has been putting my husband and mil through so much hell for really no reason because most of it is fake to get attention due to him being jealous of our daughter. and of what is real my husband need to stop seeing him suffer. so please any thoughts or prayers would be much appreciated.
