What to do when ur bff ditches u ?

I had a friend and she ditched me for no reason. There was a brake in my sport and in that brake we talked a little and then I saw her again and she sled like we wernt friends at all. We were friends for like 7 - 8 years. Plz don't say make new friends cuz I am homeschooled. My sports team is small. So what should I do?
