I'm very sorry for your loss. A few years ago I lost my best friend who was also about your sons age, she was 27, it was unexpected. I was there at the hospital that day with her mum. Looking at her mum that day I felt like I could feel just a touch of what she was feeling, and it was the worst horror I've ever felt. My heart is still broken over this. I wish I could take the pain away for her, I wish there was something I could say. We still see each other, and like to tell stories about my friend who I will never stop talking or thinking about. I will pray for you to find some relief from your pain. So very sorry again.
