One year when we were finally in the same class I saw her with two different girls - they were chatting and ignored me as I walked past. I was broken. We got to choose where we sat and she went with another girl. I sat next to the last girl left, Alice. Her best friend was sitting with another girl too. But I was cautious. I was expecting a fight, but it didn't happen. 

As she moved the phone towards me I saw that she had hurt herself. It was horrible. I never knew someone could do something like that. I screamed and asked her why. It turns out my fun, bubbly, happy best friend actually had depression. I was shocked and scared for her. Later she was calling me crying and saying how she wanted to die and didn't deserve to live. She even tried to take her own life.
