I haven't been diagnosed but I feel like I do. My period is due today and all day I've had headaches and my boobs hurt and severe depression. Like lay in my bed and hyperventilate and cry depression.
I don't know how to fix it either :/

I do take 5htp at night with a full stomach(like with a meal or it makes my tummy hurt) and that helps me sleep and wake up feeling a bit better.
