Hey, I believe you. I've known depression before from my best friend, who when I first met was depressed and suicidal. We weren't keen on each other at first, because he had a hard time trying to trust me as a friend. He gets verbally abused at home by his family, except for his brother, who doesn't abuse him.
But after a while, he really warmed up to me, and by September, we became best friends, and he's no longer suicideal. Although sometimes, I have to remind him that if he committed suicide, his brother and friends would get upset.
I believe that if you fall into despair and reach out for the rope, you have to think of how other people would react
