Period= monster moods

Becci
Hello, I was just wondering if anyone has any advice. I turn into a complete monster for 2/3 days of my period. I am irrational, tearful, hysterical at times! I feel so deeply sad and wounded by things that would never normally bother me! I cannot control it and this often ends up in me falling out with my boyfriend. I feel deeply anxious about this and I don't think he knows how to deal with me or even if he wants to deal with me anymore 😔  any tips or advice?? 
Many thanks xx
