I can only imagine what you're feeling.
It is going to hurt. If you didn't love her, it wouldn't hurt. But you did, you do, and it's going to hurt. Some days, you just have to ride the wave of the pain and do your best to stay afloat, especially in the beginning.
It will get better. Then again, I sit here over 5 months after Chloe's death and I still have days where I cry all day. I still can't get to sleep at night, because I'm up replaying everything in my head and crying. At some point, it won't overwhelm you so much, but from my experience, the hurt doesn't go away anytime soon.
The severity of the hurt will subside, but the hurt itself will be there.
I personally submersed myself in my church, and I honestly think it's the only thing that's kept me going. That's not for everyone though, and I understand that. I also journal when I'm having really really bad days. And I've been in weekly therapy, although we never really spent any amount of time focusing on Chloe's death as much as focusing on the aftermath (my aftermath was a big ol' mess), and I can't say it helped a whole lot, because I'm just now getting into the nitty gritty of being upset about Chloe's death, five months later. I'm now looking into seeing a naturopath for some out of the ordinary ways of therapy - art therapy, music therapy, etc.
And I allow myself to have really really bad days. I sit around and do nothing some days, I make cup after cup of tea and just mope. Give yourself the permission to do that some days.
Sending you a big, big hug. You can get through it. One day at a time, one hour at a time, and one minute at a time if you have to.
