Marty,
Looking at your chart -- my first impression is that you do not have mental illness , but rather you would be excellent as a healer, therapist (talk, occupational, physical, art), or researcher in the mental health field. You have a very active, restless mind and a nervous disposition, but you also have the ability to penetrate deep into the psyches of others, and the curiosity and the compassion to both study and heal.
You have a very interesting Grand Trine formed by Chiron in Cancer, Sun in Pisces, and Pluto in Scorpio. Pluto can be a problem for many people, but for you, Pluto is a benefactor. You have the ability to revolutionize your field of endeavor!
Chiron and the Sun form a very tight trine; you have natural empathic healing abilities. Pluto in Scorpio is in your 6th house of health and work -- and your 8th house has a giant stellium in Capricorn -- I sense someone who is fascinated by the mind, mental illness, birth, death, genetics. Chiron opposes the Capricorn stellium forces you to deal with all of the Capricorn stuff.
Just because you get a little obsessed about these issues doesn't mean you have them. Rather, it indicates someone who's being nudged along a path because they have a gift.
Marty, being 16 is not easy, especially when you are gifted and intense. It takes time and patience to learn how to direct and focus your energy -- and that's what you need to do. You might want to write down some of your thoughts or find another kind of creative outlet and way to vent. Yoga and breathing practices that calm the mind would be good for you.
I see a lot of talent, intelligence, and all that Capricorn is a powerful force -- when you focus on a goal, you will do what it takes to get there! Don't second guess yourself! Also -- I see an excellent income potential for you! All of that Capricorn - Cancer stuff would work well in finance and business, too.
Hope this helps...
