I had irregular cycle two years ago. I was told it is PCOS. After a 3 months of vitamin meds, and weight loss,it was normal again. I had to take regestrone to get periods last month. This month as well I'm a week late. I'm not sexually active.i  took regestrone again but it didn't work. I've gained 10 kgs in the last oneyear. I have abnormal mood swings, constant anxiety, suicidal thoughts and I'm mostly crying and depressed. I can't concentrate on anything. I can't study. I can't sleep properly. Constantly eat junk or can't eat anything. Everything seems out of control. Yes,I do need to lose weight. But it's too time consuming and  difficult if this prevails. I've exams in a week. I need to get rid of this mess ASAP. Can you please suggest something temporary for now so that present condition is resolved? I can't live with this aimlessness and this feeling of nothing anymore. PLEASE HELP ME.
