Grrrr....😩😤😢

So a while ago my so called 'best friend' ditched me. Quite honestly I couldn't be happier without her! Seriously I thought I was a butch she was and IS a paranoid,controlling,over sensitive,freaky bitch. Anyways her friend,Elle, and I are friends! And her Elle recently moved to the same village as us! So obviously at 14 we're all on social media and my ex-best friend blocked me ages ago and I've blocked her. Elle and I are friends on Instagram and Facebook but whenever she goes out with my ex-bitchy friend she ends up posting pictures and I hate seeing them cause the ex-best friends face really annoys me and it makes me sad that her and the ex-best friend do more than Elle and I do. And I don't want to be mean and unfollow her but I don't know whether to tell her this or not! 😥😔😳
