First off, i'm a psychiatrist. One of the biggest problems I see in the us is incorrect diagnoses. To be diagnosed with bipolar affective disorder, the patient must meet specific criteria. I see this diagnosis given out to patients who are clearly not bipolar. It's normal to be depressed. It's normal to have mood swings. Those two things alone do not = a diganosis of bipolar disorder. Many psychiatrists prescribe powerful medications to adults and children without thinking of the side effects and consequences.
If you or a loved one has been diagnosed with bipolar disorder, make sure the diagnosis was made by an md or do psychiatrist (preferrably one who is american and speaks english well) or a phd/psyd clinical psychologist. Do not trust a diagnosis of bipolar disorder from a family doctor, internist, or master's level therapist (msw, acsw, ma/lpc, ma/llp). These people are not qualified to diagnose mental illness.
If you're a parent, before you let your developing child take powerful psychotropic medication(s), ask the doctor to tell you about the side effects, the proper dosages, and risks. Ask a pharmacist too. Pharmacists often know more about medications than physicians. Don't just let your child be medicated without looking into the diagnosis, type of medication, and side effects. Don't trust foreign psychiatrists -- most don't have the skills to properly diagnose a mental disorder. Don't trust social workers or master's level therapists. Don't trust your child's school teachers, especially if they say your child has adhd or bipolar disorder.
It's normal to be a bratty as a teenager. A kid probably needs a swift kick in the ass, not medication. Before you medicate yourself or your child, think first and be an informed consumer. Educate yourself. Don't just trust the doctor.
Also, if you are on medication now, and it's working and helping you feel better, then why take it? Have your medications reevalauted and adjusted.
