I'm sorry that you're hurting. I don't know any deeply meaningful passages or soothing words of any kind to make it suck less. I just know that if I could shoulder this burden for you, I would.
Here's what I can and will do. I will always be here for you. I will bring you Oreos and Ovaltine. I will do ridiculous dances around the house with you. I will do lame-ass impressions at 4am, just so you can stay up for 15 more minutes. I will pull out the futon when you need to sleep in the living room. I won't judge you if you cry or throw up or get mad and want to punch things. Whatever you need, I have you covered. You know, I will just be here.
I am so truly sorry for your loss.
