Agitated

Lately I am getting agitated easily. I don't know why?
Always try to look for trouble, with my wife and also my parents.
I do not accept or even want to hear anything they said or suggest.
well, I think I am not feeling too well lately. Might need to change a doctor for my increasing aggression, or else one day if all hell break loose. I can't imagine what will happened.
I just have a fight with my wife and she is crying, but I am still trying to upset her even more.
GOD have mercy on me, I have sin a lot. And don't know what to do! I need help!
