Tricky: Without an actual examination, I cannot give specific medical advice on your particular health. Polycystic Ovary syndrome http://www.mayoclinic.org/diseases-conditions/pcos/basics/definition/con-20028841 and low thyroid http://www.medicinenet.com/hypothyroidism/article.htm as well as depression can have those symptoms and can be tricky to diagnose unless just the right tests are done
