Friends

I know this isn’t about periods and or anything but I think they could be a factor that contributes towards this. I am a 15 year old girl and suffer with Major anxiety. Recently I have noticed me and my best mate have been arguing a lot. I think it might be because we spend a lot of time together and we both have boyfriends that distract us. I think she may also have some jealousy going on as her boyfriend doesn’t attend our school and mine does but I’m not sure. Anyway recently we have had a massive argument and she broke her friendship with me and got people on me then called me a bully. Now I feel

Worthless and don’t understand fully why when I didn’t actually do anything. I feel like my anxiety and the fact that my period causes a lot of stress could be a factor but idk any advice on how to resolve things?x
