boondocks, I'm so very sorry for your loss.
I lost my father unexpectedly to a heart attack this past September and have been dealing with family issues on both my wife and I's sides since, it seems.
Sitting here in the hospital with my wife's grandmother right now. She had a third hip surgery a couple weeks ago and suffered a stroke. She's recovering physically, but is still struggling with her speech. We're hoping for the best, but still far too early to make a prediction on a full recovery.
I can't imagine what you're going through. We make our best efforts to prepare to lose those that we love later on in life, but I couldn't fathom losing my little girl.
My best friend throughout elementary school died in a car accident when he was 18. His family moved around quite a bit (father in the military). I hadn't seen him in five years or so, but we kept in touch. His mom couldn't bring herself to tell me when it happened and had a friend of hers call to give me the news. My family and I loosely kept in touch with them over the years. He's been gone for 15 years or so now. His parents came to my dads funeral and it's the first time I had seen his parents since their sons funeral. I saw her and hugged her for what felt like five minutes. It sounds weird, but I could have gone without seeing anyone else that day. They're in a good place now, emotionally, but I know she especially still struggles with his loss from time to time.
Stay strong. Keep busy. We all handle loss in different ways. Find a system that works for you and practice it. I apologize for rambling, I don't know you at all, but for some reason felt the urge to say something. I guess I'm in a weird place emotionally, but wanted to take the opportunity as many others have in this thread to say that you're not alone. You have others that love and care about you.
Take care.
