You mention your challenges right now but you haven't really mentioned anything psychic going on. What sort of psychic symptoms do you have? Do the dreams or nightmares (heaven forbid) come true?
Remember that while you may be psychic, that does not mean you are not also depressed or bipolar. People with bipolar are among the most sensitive psychics I know. Bipolar disorder seems to come along with great psychic and creative talent. There is no shame in being depressed, either. I was depressed for over 30 years of my life before I found a class that helped me change things for the better. I too have sleeping disorders - more than one! And they can contribute to depression.
I have to make the obligatory disclaimers first before I tell you anything about being psychic: Listen to your parents and doctor. Don't go off any medications.
Now that that's out of the way ... the next step for you is to learn some sort of grounding mediation. See the meditations on the Living With Your Psychic Gifts web page. Do these exercises twice a day, in addition to whatever medical treatments you are taking. It will take a while for the meditations to make a difference.
Look for books by Caroline Myss - my favorite is "Why People Don't Heal". I recommend an amazing book by James Roswell Quinn called "Controlling Others for Love and Profit" ("If you believe that, then you better wake up. Controlling others is not the solution - It is the problem."). Don't be thrown off by the title
