It is possible. BC and the hormones can cause a lot of anxiety. I went on the ring and it gave me an eating disorder. I gained a little bit of weight (Less than 10lbs). I became terrified I was getting fat. But I was also ravenous all the time. So I was obsessed with not having any food. I started hoarding it everywhere - my desk at work, and even my bedroom. I make okay money. I have several credit cards. I've never, ever been in a situation where I was even a little hungry and couldn't find something to eat. It was complete insanity. I had all kinds of emotional issues from being on BC but that was definitely the craziest.
It took a few months, but once I was off of it and it was out of my system I went back to normal, though.
