Habbibu, sorry to hear your feeling down. Hopefully you are tucked up after tea and chocolate.
It is so frustrating, waiting for your levels to come down, and I think I found it harder when my figures were low, and I still didn't know when it would all be over, than at the beginning when my levels were huge.
I know what you mean about other people, I found it very hard dealing with friends who were pregnant, even if they were the model of sensitivity. TBH I found it hard to deal with anyone, apart from dh, in relation to the molar pregnancy, because no-one has ever heard of it, it is a pretty hard thing to explain, and it just drags on for such a long time, that after a while there isn't much that people can say, it's just like a big elephant in the room, if you know what i mean!
Dd1's tree is a beautiful idea, I have never done anything to mark the 2 mc I've had, but I think that is something I like the idea of.
Take care.
