I need to talk about something

I guess I’ll give you some background. I moved to a school in like 2nd/3rd grade. I was terrified that I wouldn’t make any friends because I’ve already struggled with making friends in the beginning. But one day I’m not really too sure how I met this girl, but I met this girl. Let’s call her Emily. It’s really foggy, but I don’t really remember how we met and how we got close but Emily became my best friend. I basically grew up with my best friend living next-door to me. Life was perfect anyway fast-forward to fifth grade and my dad tells me that we are moving across my country, I was devastated. I already knew that we could already move, but I didn’t know if we were actually moving.The same night I was informed that we were moving,I told Emily. she broke down in tears and hugged me as we both sobbed. We started packing and doing all the moving stuff for like a few months. I’ll never forget how my real friends looked at me when I was entering my pick up truck to leave my life behind. I’m sorry for saying this just now, but I had a friend group with Emily in it and a bunch of other best friends that I made. I forgot to tell you guys that in the beginning, but sorry. The Friend group was very close and we were always there for one another. We had a couple fights like average, but I finally was happy and found my happy place. Until I got that news that we were moving across my country. I now live over 28 hours away from my old best friends. I didn’t have a way of contacting them for about a year after I moved so when I first got my hands on my device, I finally called them the day I got it. When I answered the FaceTime with all my friend group I found out that none of them are friends and they all hate each other now just because I split up. It may sound like a little baby story and I should just cry about it, but I don’t know why, but this genuinely made me feel guilty. I ruined a friendship. Sorry for trauma dumping, but this isn’t all of the story. I’m just not gonna share the rest right now. Other thing I will add is Emily stopped contacting me after I moved when I had my device for about two years and I didn’t even know if she was alive because she was struggling very bad with financial problems with her family and she would have really bad mental health and without me there I knew something bad was going to happen and I still don’t know if she’s ok.
