Mood Swing?

I have 45 days packed in my pocket ready for Free19, but I am currently feeling very moody and feels like even the tiniest thing can piss me off. I got into an argument with my Dad when we went for Korean Barbecue yesterday. I was trying to be nice so I throw a dish of raw meat into the grill so the rest of my family can focus on eating instead of cooking. And then my dad was like, ‘Stop being like a barbarian, fry them one at a time’. I was hotheaded and explained ‘I was just being nice’. He clearly didn’t buy my defence and added ‘If you were eating with someone else, they would think you are barbaric with no table manners’. I countered and said ‘I am not sure why helping each other is considered barbaric’. And then he complained about why was I ordering so much food, this will only result food being wasted. I know it was just a tiny thing I could have just shrug it and say ‘I am hungry and I can finish the food’. But I got furious on how he picked on something so little and complain about it, so it turned into a bigger fight (not physcial. I notice my sister was on the brink of coming in to stop us but we ended soon enough. We haven’t talked for the last 24 hours. Now my head cools down but feels like I could have done better and more importantly I should have done better, especially being on a 45 day streak. I don’t know why am I still so moody and the mood swings are really noticeable, it’s like I am on a man period or something. How can I have better emotional quality? It has always been a weak side of me.
