I've been feeling extremely moody (+ pain in the abdomen). Why? Hi, I've been really moody recently. One minute i'm flaring my nostrils out in surging fury, but then I want to drown in my own sad tears, and then i'm as happy as an angel again. I wanna know why! I have also been feeling pain in my lower belly area, if that helps (maybe its just from eating too much but i'm unsure).
