Its actually ridiculous that some loss is seen as more worthy than others.
Two of my dc have died, I donated the organs of one, and their death is seen as more 'worthy'.
There was a case in the press a few years ago where parents were fighting for their son to have all sorts of intervention etc and they gained quite a following, and when sharing the story of my other child I was told that I didn't love my baby as much as these parents love their son or I would have fought harder and my childs death was my choice, one even said her 'loss' of this child she had never met was worse than mine because I never fought like she did.
I also miscarried twins and was told it wasn't as bad as my children dying at least I didn't get that far.
I was also told after the death of my child by someone who had suffered infertility that my pain wasn't as bad as hers because at least I had felt that love for a couple of weeks and she would never feel that.
There is no scale for those of us who lose their child in whatever way, we feel what we feel and nobody has the right to judge or compare our losses whether they feel its a choice or not.
It doesn't make me feel better to think "well x y or z didn't happen to you, so I'm allowed to feel worse than you do" and I certainly never think that my pain is worse than someone else's.
We are all on this path because of circumstances we didn't want to be in. We should be united, not trying to outdo each other.
