Larrissa, my condolences to you and your daughter.
My father took his life when I was 11 and my brother was 6.
For starters, I think you should know that we are both functioning, competent adults, graduates (I have 2 degrees and am working on the masters, he has a masters), in reasonably good jobs, I am a parent, he is engaged. Marked yes, scarred yes, but I don't think anyone who didn't know would know if you see what I mean. It's one hell of a big deal, but it can be gone through and your daughter will be OK.
That said, my mother collapsed completely for years and we had to carry her through. I don't think that was good for anyone. I think in your daughter's best interests, you need to get yourself some support, quite probably professional, because you are her best and closest support. She needs you, so you need to do whatever it takes to be strong and there for her. Sorry. But in my experience, otherwise it feels like losing two parents at once. By the way, I don't mean you shouldn't cry and acknowledge your grief in front of her, but she shouldn't have to carry you.
Hope that makes sense. Feel free to ask if you have queries.
Thinking of you. x
