Suggest Remedy For Extreme Mood Swings And Short Temper

I am a married 26 year old. I have a fourteen months old son. I am very rude to my husband n sometimes to my mother n family. I react badly to something i feel is wrong. I am very honest towards all my relations n when some dishonesty or criticism or meaness is seen from some one it puts me off big time. I am raising my son so cant go out n work. My family says i need a psychiatrist thats their way of saying that i am out of my mind. I do get mad at very small things as well. What can i do?
