DO YOU THINK THIS IS MY FAULT :( !!!!?

It's not your fault. He probably is really stressed about something and is indirectly putting the anger onto you because your the closest and easiet target. Have you heard the saying "we hurt the one's we love the most". You guys are family, you'll look back on it in a few days and laugh!! Don't sweat it and DON'T stress yourself out. Just let them vent and holding the saying that everything is going to be ok at the end of the day
