to answer ur question though YES all these symptoms could be related to
pcos,
pcos will usually make u gain weight
and the skin color changes are usually due to hormone imbalances, as is the anxiety. i too have horrible anxiety with panic attacks, it does get a lil better once u get the pcos under control, loosing weight will be the most important thing! the best advise i can give u to do that is avoid sugar, carbs such as white bread pasta potatoes ect.
