I'm giving up on this life. I don't have hope anymore
Are you serious about this? What kind of hope are you looking for? Hope for humanity?
Is there still hope for humans?
That's subjective, to be honest. My answer would be there's always hope when you look hard enough.
That's sad. I've looked really hard. I'm going to give up.
Honestly, I think you have an extreme case of depression and need a doctor to help you. Head to the hospital if you're feeling like you might harm yourself. There are doctors there that can treat your depression and help you feel much more hopeful about life.
