I am a woman and I to was angry for a period of time.. unexplainable anger, lack of patience, withdrawing from others so I wouldn' t lash out on them for stupid reason.. I talked to my doctor about it.. pre-menopause ?? I noticed my pattern and made connections.. It was link to my hormonal cycle.. STAGE OF LIFE !! that was my experience .. I am glad I didn' t stay that way. I was able to understand and work on it..
