Losing a bestfriend

Me and my ex-best friend fell out... I know I was in the wrong, but I miss her energy. Jungle and I became very close over the summer; we were friends for almost a year, but I've never felt that close to someone before. Anyway, Jungle and I almost fought in front of the whole school. And we haven't talked since. But she forgave my other friend, and I understand why she hasn't forgiven me either. I just wish I could talk to her one last time. I feel like she's changing. She's more popular now, and she looks different; I didn't even recognize her.
