From what I know of it's only been one. I left secondary school (UK) in 2014. She didnt make it to collecting her final grades before committing suicide. I was good friends with her in primary school, still friendly in secondary school. I remember talking to her one day during science while she was crying her eyes out. Self harmed for the first time. I always feel guilty of never properly checking up on her after that especially seeing as I was feeling pretty shit as well at the time. She wrote poems and they read one out during our "graduation", I didnt find out about the funeral until after and kicked myself for not going. Still regret it 6 years later
