Cheese - I'm glad I can help you to cry. Crying is good for you, it releases stress and relaxes you - or so they say...
It is not sad at all to need/want to feel validated - we all need that and at times like this you need it more not less and at this time, and because it's his family, you aren't able to get your validation from DH. Whereas we can tell you exactly what wankers his family are being without feeling remotely disloyal.
If by 'doing something wrong' you mean in regard to his family, you are definintely not. You have shown great restraint - far more than I could have managed I'm sure - but it's hard to say, sometimes grief just wipes you out so much that you just don't have the strength to fight.
Of course you wouldn't have said that if it was your DC, just as you wouldn't have just stood by and watched one of your DC treat another one like BIL treat your DH. You, I and any decent Mother would have been telling him to sort his shit out, get his arse to the funeral of his niece and act like a MAN!
I have no idea how she take BIL's side and how she could say that to you, but I'll tell you one thing for sure, it would be a cold day in hell before either of them set foot over my doorstep again. I would tell DH that and tell him if he wants to see either of them he's free to, of course, but I wouldn't be. There's no excuse for either of them.
Of course you have changed - you will never be the same as you were before you lost Scarlett, however, you will get your Mojo back and be much much more like the 'old' you. You learn over time to live alongside the grief, but it will never be 'not there'.
You were 'overlooked' and some fuck muppet actually said that to you? I despair. Honestly, how bloody insensitive can some people be?! I do hope you get the PM soon, it does feel like one less thing you are 'waiting for' and it will hopefully give you some idea of what went wrong - even if it just confirms it was her cord :( Maybe it will help you to stop going over things in your head, once you have some answers.
Going through the birth of a baby you have already lost has to be one of lifes very worst experiences. It is beyond cruel still having to go through the birth :(
Of course it doesn't sound 'stupid' not to have wanted to take more than G&A as you would have if things had been different. I think you were incredibly brave though, I think I would have wanted to be drugged to the max - but who knows? You can't know until it's you.
I understand what you mean about being scared of going too far - I felt the same, then one day it just crept up on me - I was alone, no-one else to upset with my grief and I lost it - big time. I was in my car in a car park and I was in a right state - but eventually you stop - you just run out of energy :(
Lots of love & hugs
Chippy
