Suggest Treatment For Hair Loss And Mood Swings

i was suffering from hair loss and mood swings, also suffering from acne and hair growth on chin and neck and had put on a lot of weight that i just can not seem to shift even though i eat healtily and not large portions. as i am only 33 my gp tested me for pcos and thyroid and the first lot of results came back with everything normal but male hormone in higher regions of normal. went for tests a few months later to rule it out completely and results came back serum sex hormone binding globulin level low. i asked what this meant and all the doctor said is they had never heard of this before. please help i am none the wiser and on having a quick look online i can see it could be an indication of pcos or hypothyroidism.
