My little brother died two months ago. We were raised in a tumultuous family, so we were really all each other had. He was by far the most important person to me in the world. I feel like I can't move forward. I am in pain constantly. I look for him everywhere and I am constantly flooded with guilt for every time I wasn't nice to him. We mostly got along really well, but we are brothers so of course not always. He died on his motorcycle at just 18 years old. He hadn't even graduated high school yet. I feel so alone. It's like my heart has been ripped out of my chest and I don't know how to sew it back up.
