Why am I such a bitch during periods?

Seriously, is there any way to change my attitude before and during periods? I’m so sick of being so irritated and cold to others, I know it hurts them. I genuinely feel like this is not normal( not on that scale), but nothing seems to work. Once i’m over it- everything is fine, but during, I’m feeling like a worst person ever, i’m so so so guilty. PLEASE HELP!!!
