You never stop loving or missing the one that died.
I literally can’t imagine how hard it is on parent’s whose kids are actually sick, suffering so badly, and then may end up dying. I don’t know...I’m not sure I’m made of stuff strong enough to deal with that.
I think the sentiment here has a lot of truth, but it's just a bit too strong.
My parents lost my sister when she and I were young. It was terribly painful for them. It still tears me up to think about it. I think I've only ever asked about it once or twice in 40 years, and especially never dared to do so with my dad. But they seem to have found ways to be at peace about it. They are happy in their own lives and happy about me. Time and love and wisdom can eventually make it OK.
I’m going to have to disagree with you here.
On one hand having another child or more children could be comforting, but I think you are more likely to make that child’s life much harder and sadder, which would add more guilt. It’s all around *ucking awful and terrifying.
