No. That is NOT enough to diagnose you as bipolar. Without the presence of at least one manic or hypomanic episode, the diagnosis bipolar disorder cannot be made. Period.

Here is the diagnostic criteria for mania:

A distinct period of abnormally and persistently elevated, expansive, or irritable mood, lasting at least 1 week (or any duration if hospitalization is necessary).

During the period of mood disturbance, three (or more) of the following symptoms have persisted (four if the mood is only irritable) and have been present to a significant degree.
1. inflated self-esteem or grandiosity
2. decreased need for sleep (e.g., feels rested after only 3 hours of sleep)
3. more talkative than usual or pressure to keep talking
4. flight of ideas or subjective experience that thoughts are racing
5. distractibility (i.e., attention too easily drawn to unimportant or irrelevant external stimuli)
6. increase in goal-directed activity (either socially, at work or school, or sexually) or psychomotor agitation
7. excessive involvement in pleasurable activities that have a high potential for painful consequences (e.g., engaging in unrestrained buying sprees, sexual indiscretions, or foolish business investments)

Hypomanic episodes have the same symptoms as manic episodes with two important differences: the hypomanic mood usually isn't severe enough to cause problems with the person working or socializing with others (e.g., they don't have to take time off work during the episode), or to require hospitalization.

These are copy-and-pastes from this site and the DSM--the Diagnostic and Statistical Manual of Mental Disorders. It's the "psychiatric Bible" and also what insurers go by in their coding for payment and billing.

A second opinion is a great idea. If you have further questions, let us know.
