A couple of days after my period ends, I feel angry, stressed, and irritated. Over time it gets worse. The week before my period begins it has become so severe. I feel tired, unfocused, noises are painful to me (last time I kept hitting my head and pulling my ears to stop the noise) aggressive to the point of feeling an urge to stab someone, i even have some suicidal thoughts and find myself crying for simple things. When my period comes, I feel better. All that negativity leaves.
