Is it wrong to want to go to bed and never wake-up?
I am concerned that you are saying this, why don't you want to ever wake up?
Why would I want to live in a world where my father is so unhappy
I can understand you're in pain, but wanting to die not the way to deal with your problems. You should try to speak to your father and work things out with him.
It would be easier to think of him as not existing.
Suicide should never be an option, you have to try to keep fighting. You should use your dad as a reason to live and help them to be happy too. Along the way, you might find a greater sense of purpose for yourself too.
