The only way to be diagnosed is to see a psychiatrist
and be assessed. There are many drugs used to treat
bipolar disorder. Some are
Seroquel, Abilify, Lithium, and Risperdal, though there are many more. Depression is just being down and sometimes having a normal time between periods of depression. Bipolar disorder has depressive episodes but also hypomanic or manic episodes. I would suggest going to NAMI.org for more information.
