When mood swings don’t make sense

These last few days my mood has been so unpredictable and I can’t figure out if it’s stress taking over or my hormones shifting again. My body feels sensitive to everything and even small things throw me off. I’m trying to stay grounded with simple self-care, but the emotional ups and downs are draining.
Has anyone else noticed their mental health shift wildly when their hormones are out of balance? What helped you stay steady?
