So sorry to hear all of these stories
for everyone going through this. It is utterly devastating, but you do get through it.
I had my sixth last month, each has affected me very differently, number 3 this year I went utterly numb it almost become "normality" get pregnant have a miscarriage and I didn't even cry, number 4 has utterly destroyed me, but I am feeling more on an even keel at the minute and will be trying again any day now.
I am having counselling and that has been very helpful, I know many places do have group sessions and would suggest this as a good place to listen to other stories, mumsnet has been such a great place for support and I don't think I'd have managed without his forum and the most important one for me, talking to my partner and listening to him - it effects men very differently but it is equally as heartbreaking and for my DP watching the person he loves physically go through it and not being able to do anything about it is very difficult for him. If your partner is pulling away a bit it might just be that they are trying to be strong for you, when he started talking to me it helped us both.
And finally, you just need to be very kind to yourself, it is very ok to feel sad.
I have a necklace which has a tiny birth stone for each of my babies due months. I am useless with plants and not sure if we will live here for ever so a necklace is something I can always keep.
I'm so sorry again for your loss, but you do get through it, not over it but through even if you do have sad days X
