Dildals, I'm sorry it got to you. It's very hard to convey tone with words on a screen. I'm worried I'll say the wrong thing but to be honest, I'd rather get it a bit wrong than say nothing at all.
When I lost my second baby I had DD1 at home, she was older of course, but she kept me going and was my raison d'être. Bella is the same for you, she is a very bright light in the darkness and your joy in her will naturally lead to all sorts of truly conflicting emotions, although they clash they are all valid in their own right and don't diminish each other.
It is very, very soon. You are still in the midst of all this and you will be at the mercy of your emotions for some time yet. You say you don't know how to talk about it, perhaps you shouldn't even try yet? I couldn't talk about it for some weeks, I could only cry and after an extensive cry I'd be able to talk a bit. DH and I were both trying to look after each other and process our own feelings which was tricky but if it's any comfort, it did ultimately bring us closer together.
I think with the crying it's best to let it out. I visualised it as a geyser, it would erupt violently and then I'd have some calm as it all built up again before the next eruption. What happens is that in time these eruptions become less violent and less frequent and you learn to manage what has happened somehow. You will not be in the state you are in now for the rest of your life, but you will be in it for some time yet and maybe it's easier to accept that rather than fight it back.
Behave however helps you best with other people. If you don't want to share your grief then don't, it's yours and can be as private as you wish. I found that sometimes it was useful to be honest with people and say 'I can't carry on this conversation as I will get upset and I dont want to get upset at this moment.'
Anyway, I'm going on too much.
I hope Bella had a good night and you enjoy your time with her today. How is your own physical recovery going?
