Emotional problema

I was recently diagnosed with PCOS, and the doctor said it's not a big deal. I only have to take my birth control daily and things will be fine. But she never told me that using birth control plus the PCOS symptoms ( which I've already had since I was younger) would basically put me through a second puberty of emotional drama. I don't struggle with weight, but I feel like in not pretty in any sense, stupid, useless and slow. Any emotional situation makes me cry. I am extra sensitive and I hate it. I don't know if I'll get used to it or if it will go away.
