Is it normal to feel left out in this situation?

I recently lost a family member who was a big part of my childhood. After our that we kinda drifted apart. Well, they grew out of me. I held onto the memories though. And this person has reached out to me a few times over the years. Now that they're gone I feel hurt because their immediate family and current friends that they had seem more important. I'm not saying they shouldn't be but I feel distant from my relative now. We were really close as kids. I was there for their whole childhood, spending summers, weekends, and events together, just us two. It hurts that I seem irrelevant because I hoped we'd eventually hangout again since are in our 20's and had time. I feel like I lost my best friend.
