endometriosis
"Effective for birth control and less painful periods, but HOLY moly, NO NO NO  on depression and acne. I've been depressed before, but this birth control made have thoughts of suicide for the first time in my whole life. I felt like crying for no reason every day, I thought life would be better for everyone if I weren't here anymore...  I stopped taking it for 2 weeks, and for the first time in months, I feel like myself again. I feel like my head isn't on sideways, and I feel better. More energy, happier, no crying... My face broke out like crazy and I've always had normal skin. Not worth it for me. I'd rather take a few days off every month due to painful cramps than be crazy and pimply."
