I am 42 and started YAZ three weeks ago. Since starting the pill I have been seriously depressed! I have no energy, no desire to see friends or go out, I have no energy to do any of the things I normally love to do. I have no reason to feel so down! Life is good. I wondered if YAZ could be the culprit and then I saw these postings (thank you for sharing!). I have no doubt YAZ is making me depressed. Other symptoms I have are daily headaches, mood swings (crying, no patience, anger),lack of concentration, forgetfulness and no sex drive. I plan to finish this pack and stop. I started YAZ to help control PMS which seems to be getting worse as I get older. I'd much rather have PMS for 6 days than feel this horrible the entire month.
