I opened up about my mental health struggles a few months after the attempt of my younger sister. We had been friends for 10 years at this point, I thought she'd understand even though she had never experienced depression, anxiety, and PTSD on her own. She didn't. She invited me to a party she was holding the same night I told her, she told many people about my mental health struggles that I didn't want to know. Another one of our "friends" mad-dogged me the entire night, whispering to others about me, leaving a room if I'd walk in, dirty looks, etc. just because I didn't tell her about my struggles. She was upset I didn't trust her, so she bullied me. And my best friend of 10 years gave her the information she needed to make me uncomfortable, which was inevitably my own mental health. I haven't spoken to them, or anyone associated with them, since that night.
