So moody...about 1 week before my period, I feel 100% depressed. I cry for no reason, my mood will change from happy to angry/sad at the drop of a hat. I've been on desogen for about a year and my boyfriend has said there has been a noticable difference in my mood. I feel horrible about myself, my relationship, everything...and this feeling of doom is like clockwork - 7-10 days before my period. I'm switching.
