Wow, Ping Pong! That is definately some family history of cysts! It sounds rather indicative of PCOS. That could explain your weight gain as well. I gained weight despite exercise and a healthy diet/lifestyle, stopped menstruating, developed chin acne, developed strange anxiety, especially during menstruation, nauseated all of the time, and more than usual hair shedding.
I'm insulin resistant. My body doesn't metabolize sugar properly. I take cinnamon for proper blood sugar metabolization and fish oil for various related and unrelated PCOS issues. Thank God I don't have to take metformin or any other meds for PCOS...just Ortho Cyclen. I have a pretty mild case of PCOS, thankfully.
And Ping-it would also explain the anxiety and panic attacks you sometimes get. Not saying YES! You definately have PCOS!, because PCOS has so many broad symptoms, but it is a possibility.
