Cleansing diets symptoms and conditions

Im 20 yrs old and started taking Yasmin last fall. i was on it for 7 months and finally stopped due to 15lbs weight gain, extreme depression, and nausea. i have been off it for 6 months and haven't had my period since. i have also had extreme loss of metabolism, ive never had this much difficulty losing weight, after all the cleansing diets and working out every day! i would love to know when this crap will finally be out of my system so i can get back to having a normal, healthy life. if anyone has useful input about thins let me know!
