Stress, depression, and your
menstrual cycle may all be linked but what is causing what may be a bit more complicated. My cycle causes my moods to go absolutely wild. I'm all over the board with sad, mad, irritable, etc. I eventually got diagnosed with PMDD and put on meds that were a lifesaver. My friend on the other hand, has clinical depression and when she is having a bad time, it can cause all kinds of menstrual issues.
