This might come across as rather corny, but there's a lyric in one of Tupac's rap songs that goes as follows:
I once contemplated suicide, but when I held that 9 all I could see was my momma's eyes.
It was a line I never gave a second thought to until I realized "the truth" wasn't the truth. I was borderline suicidal at that point. I never took steps to carry it out, but I didn't want to live anymore. Dying in my sleep would have been a welcome relief.
But during those dark times when I contemplatee how I would carry it out, I kept thinking of how much it would affect the loved ones I left behind. It wouldn't be fair to them. It doesn't even occur to you until you're in a really dark place.
Things got better. It took some time, but things improved. I haven't been anywhere near that level of depression in nearly a decade.
