My mom suffered from severe depression for a few years in my high school days. Every day I would fear leaving the house because I thought she might kill herself. One day, I got pulled out of class by a family member and was told that she found ambulences and fire trucks outside my house on her way home. My heart stopped.
She hadnt killed herself, but she had gone catatonic in the bathroom. It was the scariest moment in my life. She was on some medication at the time.
Depression is a serious fucking thing, and bad prescription is even worse. sometimes she would leave the house and just forget to stop, coming back many hours later. It was all from bad prescription except the first couple months and it lasted upwards of 3 years.
I am sorry for your loss... the medical industry can fuck a lot of shit up.
