I hope one day there might be alternate endings. Not saying it SHOULD have them or that it's BAD that it doesn't. You create what you want to create. But I personally wish the player character could have a choice in the end. That the choices could matter. That your character could eventually open the exit door and step outside, or finally find the courage to ask for help. It's not my game. I can't tell anyone how to create. I just find it sad. I'm intimately familiar with the kind of pain that makes you feel like there aren't any choices but the one you should never make.
You have to fight anyway. You have to choose not to do it, even when the only other option seems to be a lifetime of suffering. You still have to choose not to do it.
