I believe that it may well be hormonally related, because it started around 14. I recommend the chapter by Dr. Hyla Cass - See: "NATURAL HEALING FOR DEPRESSION" - Stroehecker - *SEARCHBAR- WWW.AMAZON.COM (largely about NATURAL HORMONE TREATMENT) provided the best overview of hormonal imbalances in females that I have encountered in decades. Enter her name in the searchbar at amazon; I also recommend her latest book, or audio course: Eight Weeks to Vibrant Health: A Take Charge Plan for Women to Correct Imbalances, Reclaim Energy and Restore Well-Being by Hyla Cass MD and Kathleen Barnes (view http://alternative-complementary-health.… ). Read: Natural Prescriptions for Women: What to Do-- And When to Do It-- To Solve More Than 100 Female Health Problems-- Without Drugs by Susan Berg and The Editors of Prevention Health Books, from your bookstore, or Amazon.com.

There may be no single answer to your problems, but the sensible approach is to test for vitamin (optimising vitamin D3) and mineral deficiencies; correct, and ensure good levels of Omega 3 fatty acids. Dr. J. Cannell advises that the co-factors necessary to optimise its absorption, and utilisation are magnesium, zinc, boron, and vitamin K2. I recommend using either health food/vitamin stores, or Googling: " ... ; supplies" rather than risking any old, or substandard products at supermarkets, or even on pharmacy shelves.
The best dietary source of vitamin K2 is natto. View http://drbenkim.com/vitamin-d-facts.htm Grassrootshealth D action www.grassrootshealth.net/daction offer cost price postal 25(OH)D testing. Take at least 4 Omega 3 fish oil supplements, daily: (certified free of mercury) it is best if consumed with an antioxidant, such as an orange, or its FRESHLY SQUEEZED juice. If vitamin E is added, it should be certified as being 100% from natural sources, or it may be synthetic: avoid it! Similarly with vitamin B; ensure good levels of folate are maintained. Females may benefit by balancing the DHA, & EPA versions of Omega 3 in fish, or krill oil with ALA flaxseed oil Omega 3, or at least one heaped tablespoonful of ground flaxseed, daily. Vegetarians: Google: "Omega 3; algae; supplies" Check out "krill oil" via the searchbar at www.mercola.com which is far less easily oxidised, so more is absorbed; from health food, or vitamin stores. Vegetarians: Google: "Omega 3; algae; supplies" and use it with flaxseed. Stabilise hormonal levels with bioidentical hormones from a compounding pharmacy; consult a naturopath. In the meantime, or if hormone treatment is not an option; use the effective natural core treatments for depression at * http://your-mental-health.8m.com/blank_27.html (anxiety/worry; see pages 1, & i). If using a RECOMMENDED* brand of St. John's Wort (take with meals to avoid possible stomach upsets; check out the websites on St. John's Wort via page B) view the websites about it on page B, and if using UP TO 50mg of 5-htp daily in addition (or UP TO 200mg of 5-htp if NOT using the wort) take with a very low protein meal, to maximise the amount crossing the blood/brain barrier, with no, or extremely little protein 2 hrs before, to 2 hrs afterwards. You could also use SAMe with the core treatments, but not with anything else.
