I think about my friend Brian a lot. He took his own life not too long ago. I wanted to help him so much but I couldn't fix him. I even told him as much. I get depressed too but nobody can fix that besides me.
He was much more entrenched in his mental illness then I was at the time (I have been suicidal before), and he couldn't get out of it. He gave up and let himself drown in it.
I will always miss him.
