My son died before he was born, so not the same situation. It's been two and a half years. I can't promise you it gets 100% easier/better. It doesn't. You'll start dealing with it in a different way - bring able to smile when you think of her rather than crying, for example - but the pain doesn't fully go away. You'll always have some piece of you missing. I don't say this to scare you, to crush your hopes for the future. It DOES get easier to handle. You WILL be happy again someday, though not completely healed.
It's like a scar from an incredible wound. It hurts massively at first, so much you don't think you'll be able to stand it. Then it starts healing, not completely, but enough that it doesn't bother you as much. You might have days when you want to pick at it, focus all your attention into the pain. That's okay. Other days you might not even remember until something reminds you. And one day, you'll realise the raw pain has subsided, faded into a scar you'll carry for life but have come to terms with.
I'm so sorry you're going through this. There is a massive amount of support around here, please use it. Talk to us. Reminisce about your darling girl. Know you're not alone. :hug:
