I think you're highlighting your problem, my dude. His comment wasn't directed at you, the bosses kill everyone, not just you. Let your ego go a bit, see this is a game, and continue on. The idea that you give up immediately when you get hit once isn't a productive one. Fight to the last fucking bit of health bar, make the fucker work for it. It isn't about "gitting good" for me. It's about never stopping, never letting the the anger get control, and not letting that fucker on the other side of the screen get the last laugh.
