How do suicidal tendencies start with depression sufferers?

Having lived most of my life with depression and that word that has become damaging to me & my family...suicidal. Yes after so long I can sense that I am about to go down the rabbit hole. I lose interest in everything n everybody. I feel like a burden, that I don't matter to anyone, no accomplishments in life. That my family would be better off without me. I start to feel emotionally tortured, no good thoughts can be found. Backed into a dark corner. Lots of crying begins, over the slightest things. And that is just the beginning.

They might think of themselves as worthless. They also might feel like they hate themselves or that life isn't worth going on with.

Signs of suididal tendencies can be cutting or talking about suicide or death.
