I'm so very sorry for you.
I wish I knew some words that would ease your pain, but I know none.
I wish I could give you some advice about what to do to ease your pain but I know nothing.
Time does dull the pain but the pain never goes away.
It's been over ten years since my Wife died and I was crying for her a couple days ago, as I am doing now.
There is no easy way to lose a loved one.
My Wife died suddenly. I didn't have time to say Goodbye. That wears on me.
My friend's Wife, my Wife's best friend, later died slowly and painfully over two years with cancer. A terrible way to die.
Just do the best you can and lean on your loved ones for support and support them.
