My daughter was on Yasmin for approx 3 years for painful periods....

The same thing happened to me when I was on orthotricyclen. Your daughter has my sympathies!

I do not think this is a side effect of Yasmin or any birth control. It just might be depression or another mental illness. I have been bipolar for 10 years before I took Yasmin (which I have been on for 3 yrs now). It could also be severe PMS.

Thanks for taking the time to let people know. I also experienced serious depression on Yasmin, but luckily due to non-stop menstration after taking it I stopped taking it long enough to notice the depression. The physical exhaustion and other side affects of 4.5 week depression made it really difficult to know whether it was simply physical or also emotional trouble I was in. I stopped taking it after one month and now don't feel 'right' (it's been a week since I took the last pill) but I am feeling much better. Better enough to think clearly about what happened.
