Talk to a therapist: to explore the trigger for your depression. Perhaps you have low self-esteem related to being overweight, having an ulcer, having adult acne.& feeling cold. Also see your OB/GYN doctor to rule out Polycystic Ovary Syndrome. See http://www.nlm.nih.gov/medlineplus/ency/article/000369.htm. PCOS can cause overweight or obesity, acne & depression.
