Best Friend

So ladies I was in a bad place and i was staying with my best friend at the time. I love her so much and I know she was dealing with some stuff too. But one day at school I stared my period and she was mad and was not helping me with but attitude so I told one of my friends "She was not helping" and they told her and she got mad she told me I was being disrespectful to her and her family. So now she don't want to talk to me she said she needed time and I said ok but i have not talk to her all summer and I go back to school in 2 weeks and want my bestie back. What should I do??!
