Adolecence symptoms and conditions

I started the pill when i was 14, trying to control my cramps and acne. I have now been on the pill for 4 years. I constantly felt depressed and "blocked" in everything in my life. I gained over 40 pounds in my adolescence and never knew why. I'm taking control of my life now and have lost about 20. I went off the pill about a month ago and I can say with all of my being it was the best move i ever made. Then the acne came. I was devastated. I went back on and feel blocked again. My weight loss has come to a fault and my cravings are out of control. I am going back off of the pill again immediately. However, i don't want my acne to come back. Does anyone know of a great way to control it? creams don't really work for me so I'm not sure what to try. Mabye an herbal remedy? Any suggestions??
