Out of control

I don't understand how I got to this point. It's all suddenly got way out of my control. I can't hack this.

I went to a mental health wellbeing course. It was whilst I was there I realised just how much I screwed up. Not one person in that room had worked a full time job. They were what you expect when you think of people who have mental health issue. When/how did I turn into that person? Since the session I have struggled with thoughts of cutting myself. It's all I want to do. And I am tired of trying to find distractions. I am tired of trying to keep going for people, I am tired of being strong. I just want the world to fade away! I can't do this any more.
