My deepest condolences < 3

Very sorry to hear this 

It's ok to scream, let it out.  
My condolences to you and yours.

We're here for you.

I'm so sorry for your loss and that you're having to go through this grieving process. I hope your mourning lasts only as long as it needs to be and is soon replaced with all the beautiful memories you made together. (And I echo MK's thoughts.)

Even though I never know what to say in moments like this, I would like to express my deepest sympathy and condolences to you.

My condolences and thoughts go out to you.
