Relationship ruining mood swings over here! Help! They can be under control for months and the voila! They appear and I lose my job or make myself look seriously crazy! Gah! Has anyone had success in stopping this from happening? I know that it's PMDD because within 2 days of the episode, I get my period! I have been working so hard to get my BS at a major University and I just prematurely quit my research associate internship because my boss was a bit frustrated with me. Any advice?
