Depressed

Nate royally screwed up last night and cost me a forum member. I blame him for me being distressed, but someone else says I can't just say its his fault I'm depressed. But who else can I blame? Hes the one who messed up. Hes sorry and remorseful now, but its still his fault. Hes normally the most calm, rational person here, but he snapped and said some things he shouldn't have said. I dunno what came over him last night, except my anger bleeding over to him. But even still, he knows better. Hes main admin because he knows so much better than I do. I'm the one who has issues controlling their temper, not him. I'm very angry at him for this.
