Can’t stop crying 😢

I don’t know what is wrong with me. I started my period yesterday and even when I’m on my period I NEVER get emotional. But I feel like just running away or hiding. And everything is making me cry. Like I can’t stop. And my two year old daughter keeps coming up to me saying, “it’s ok mommy. Don’t cry. I love you.” Things that I tell her when she’s crying, and NOW I’M CRYING EVEN MORE! There is literally no reason for me to be crying other than feeling completely overwhelmed. Any tips on combating the blues that I am feeling?? I don’t really get a moment to myself between my two kids.
