Need some advice

I (23F) have always have very regular and normal periods, no cramps no nothing.

This year has been different, the week coming up to my period is absolute HELL, I get SO moody, hungry and extremely sad and have the worst thoughts, I even underperform at work. Nothing seems to be helping my mood which is my biggest issue. Hunger and cravings have been solved but my mood goes crazy.

I also don't use any medication and am not planning on using any to get better :)
