I Have Got A Hormone Imbalance

Hi, I am thinking I ve got a hormone imbalance. I ve had symptoms for about 6 months now, but I feel they are getting worse. Recently I ve had trouble sleeping, and my ability to handle stress is so low. I get anxiety and depression and mood swings. I have irregular periods and my hands and feet are always cold. I was wondering if you d reccomend me having some tests done. I d really like some help with how I can deal with these symptoms because it s impacting on my university perfomance a great deal. I m 18 and not on the pill or any medication at all, and I have a relatively healthy diet and lifestyle.
