Losing a child

Can someone please explain to me why, when you loose an adult child from alcohol problems, no one wants to know?.
The only explanation is, they were a grown up, they knew what they were doing???
I will never accept my girl would leave her baby girl!!;

Hi Birchwood -
It’s an illness and if it was their child who was ill it would be a different story. People can be indifferent and selfish on times with zero compassion!
