Bad periods to the point where you have trouble functioning, socializing and/or severe agitation, irritability, depression, etc.? And at what age did this start for you?

I would say I struggle with mine on a daily basis starting ~14. I don't know what others experience. (I'm pretty sure that BP runs thru the entire side of my grandmother's family including mother, uncle. My PDOC doesn't seem to really care about that which I can not understand.)
