Suggest Remedy For Irregular Periods And Weight Gain

Hi, I am 25 years old. i had problem since I was 18. I have not had a regular period since I was 17 . I became period very late and I had been under treat of doctor for this problem since I was 18. I hadn’t experienced sex with oppose sex at all.Honestly, I have had masturbation since I was 15. But for years I didn’t do that (from 19-24).But unfortunately I have done this habit since 1 years ago for example 2 times in a week.I read more a bout the consequences of masturbation and the methods which I can use for give up this but unfortunately in these days I should stay at home and study so sometimes I become tired and something push me to do this.As I explained I have PCOS , fortunately until 6 month ago I have not used the drugs ( medroxy progesterone) I have had period every 40 days until now. This month I should become period in 18 November and I feel very bad now I am nervous I become fat , many acne on my skin, ugly and …. . in this month I gain fat and my weight start to increase. I think every day I become fatter than last day. My weight and being in a good shape is the most important thing in my life. Today I have masturbation .i had plan to go for walking but when I go out I become nervous and ashamed myself that I have a very ugly body I lose my self confidence and came back home. I don’t know what should I do to lose weight to get read of PCOS and have regular period without being worry a bout the delay of it, and give up masturbation
