I am also young and have had all your symptoms as well as a few others. I found out about 5 years ago that I have PCOS ( Polycystic Ovary Syndrome). There is so much more information on the internet now than what used to be. It is so important that you get diagnosed as soon as possible. I would also suggest that you work with a specialist that knows about PCOS. Birth control is not the answer. Proper health habits, such as regular excersize and healthy eating, along with a medication such as Glucophage may also be recommended to you. I was on medication for about 4 years before I was able to get off of it. Now I am able to control my PCOS with different supplements and diet/excersize. I would also recommend going on a full body cleans. After doing one myself, I noticed significant differences. I am definitely not anti meds, but I believe that they are a tool to getting things started in a different direction. If you have anything at all that you need or would like information about, let me know.
