A previous answer follows, modified for you: It's alright to OCCASIONALLY tell a close friend that you are feeling down at the moment, and ask if it happens to them, and what do they do about it. Professional advice is to go out with friends regularly, even if you don't feel like it much. In "Feeling Good - the new mood therapy" by David D. Burns, M.D., from your bookstore, or Amazon.com, he recommends that you estimate beforehand how pleasureable it will be, out of 10. Then, some few hours after returning, rate the actual event. Keep a journal for this, and the other things he advises, and examine your progress. There is a relationship between melatonin, which is produced by the brain during sleep, and the neurotransmitter, serotonin, which has been shown to be low in people suffering from depression. Although pre-teens need around the same sleep time as adults, teens may need up to 9.5 hrs. Many teens are naturally predisposed to, or prefer to stay up late, and get up late, but societal, and school demands are such as to often preclude this. Some schools are changing their timetables to accomodate this, but they are, so far, few, and far between. Get bright light on awakening, preferably for 2 hrs, but at least 30 mns, to reset your circadian rhythm. It's also a good idea to get bright light again in the evening, so you cover a daily span of 14 hrs; say 7 - 7.30 AM and 7.30 - 9 PM, then reduce light levels to simulate approaching darkness, in preparation for sleep. Depression impairs cognitive functioning, and can cause insomnia, which is addressed on pages 1, and O, at http://your-mental-health.8m.com/blank_25.html Take the depression quiz at http://www.blackdoginstitute.org.au or http://www.real-depression-help.com/depression-test-for-children.html and print the result. Take to a doctor, for tests. I advise against the use of antidepressants for those less than around 24 -25, due to their increased risk of suicide, homicide, or aberrant behaviour. If antidepressants are offered, say "thank you very much, doctor", and pocket the prescription, but don't fill it until giving the alternative treatments a good tryout.
Antidepressants will still be available, if required, (unlikely) but it's best to avoid the risks, and side effects, if at all possible. I only recommend their use as a treatment of first choice in exceptional circumstances. Check out: http://articles.mercola.com/sites/articles/archive/2010/05/08/robert-whitaker-interview.aspx and related articles and http://suiciderateup.wordpress.com See pages 3, and b, at 8m.com, for effective, non medication based depression treatments (self harm/cutting; see pages 1, & A). Try them for 3 - 6 months, to see if they are sufficient. If not (which is unlikely) the core treatments should still be maintained, as neither antidepressants, nor St. John's Wort, nor supplements should be relied on as the sole treatment for depression. Always check out medications first at www.drugs.com & www.rxlist.com & http://mediguard.org and read any inserts, or labels. Be on the alert for any of the abovementioned effects. I suggest that you use the many teen resources on page 2, at 8m.com. Most people these days are deficient in vitamins, minerals, and/or Omega 3 fatty acids, so a sensible approach is to test for, and address any which are found, because they may well be the cause, or exacerbating the depression. Note that St. John's Wort usually takes 2 - 6 weeks to start reaching maximum effectiveness, and there are things you need to know about it, so don't just pick up the first one you see in a supermarket and expect instant results. Check out the information provided, particularly the SJW & HYPERICUM websites, and choose an EFFECTIVE brand! Perika, Jarsin, or Kira are recommended. See http://wiki.answers.com/Q/Can_you_take_St_Johns_Wort_and_5-HTP_at_the_same_time Google: "St. John's Wort; 5-htp" Teens tend to want things: "right here; right now" and 5-htp acts quicker, but use a maximum daily dosage of 50 mg.
