How do you overcome your when dealing a difficult challenges?

I over come the challenges I face on a daily basic like depression, hate and suicide is what consumes my life. I used to be happy and have a real smile plastered on my face now its too hard to even see my self in the mirror with out thinking to my self maybe if I change maybe someone will love me forget my scars and pain that I hide behind my smile. I over come these by reading or writing out my feeling that I cant tell anyone else bc no one will listen to me when I am crying so I just place my mind In a path of dark ness and to ensure it stay quiet I am completely still. I am calm I am okay I repeat to my self over and over again. Because I know when I get through this everything will be okay.
