Friend issues😩

So..... first off sorry this may be long but please read it!!!!! I know it doesn't sound bad but I did not put all details in and this is much worse then you probably think. I'm going to start way way back to 2nd grade (I know it sounds pathetic😂). Anyway, in second grade I had a best best friend and I literally dedicated everything to her then that next year she switched schools and I still had friends, but I was too depressed to do anything about it and sorta pushed my other friends away and each year lost more and more friends. By 5th grade I was pretty much alone. But luckily this other girl saw me sitting alone in every single class and worked up the nerves to come up to me and we weren't exactly friends yet, but she was so sweet ( let's call her friend 1). Anyway later that year friend 1 got into a HUGE fight with her friend over something really stupid and started drifting apart. So friend 1 came to me, and she saved me and that year I also made other great friends, but I'm most thankful for friend 1 . So later that year we were still besties. That summer I went to summer camp and friend 1 couldn't come because she was going to Brazil and Africa just for a family vacation. So I went to camp with a few other friends (which was for 2 months) and I got really, really close to this other girl who I literally told EVERYTHING to and she also went to my school and we where friendly in the hallways and stuff but not ever that close before camp (let's call her friend 2). So at the end of camp friend 2 and I face timed almost every night. Eventually school started and I saw friend 1 again and the school year started off great. Later that year friend 1 & 2 got closer to each other and we had formed a small friend group. Later that year something happened between us and friend 2 started ignoring me and friend 1 because we all got into a small fight but it turned out to be really big. Then me and friend 1 started to grow apart because she got closer with the other girl who she fought with before. And that all happened right before the summer of 2017 which was this summer. Later i went to summer camp with friend 1 & 2 and friend 1 and I started getting closer again but then something happened and we got into another fight. She told me that at the beginning of that year she was jealous of friend 2 and me so she went home every day and cried. After camp was over and school started none of us were fighting anymore but there was awkward tension between all of us. I started getting closer with friend 2 but friend 1 is still to close with that other girl who she got into I fight with in 5th grade, and barely gives me any attention, but in the middle of classes I sometimes catch her staring at me and when I look over she looks away. I love her so so so much and I don't know what to say. I really want everything to go back to normal. What should I do?
