I'm checking out of my life
I'm sorry to hear this, why do you want to check out of your life?
Life is just too hard, I don't find enough time for sleep these days
Life is hard and it is difficult to know what to do to make things better but it is not good to just give up. It is better to seek help from others and have a better life.
I'm tired of life and the numbers. I'm checking out of humanity.
I urge you to call someone you care about and talk to them about your depression. It will help you feel better, I'm sure of it.
