In my experience as a patient and as someone who has worked with mentally ill teens and adults for many years an additional dx - if you are given one - would likely be in addition to your BP dx. That said, only your pdoc can decide upon your full diagnosis.

Bipolar 1 usually means that the person experiencing symptoms has much more hypomania and/or mania (or exclusively hypomania and/or mania) than they do depression. In addition, BD1 can manifest as some type of mania along with hallucinations, delusions, etc.

BD2 generally indicates that the patient experiences both hypomania and depression, either equally or (oftentimes) with more depression than manic symptoms.

BD NOS is not intended to, in any way, belittle the symptoms you are experiencing. Absolutely not. I know someone with severe symptoms that torment her; her dx is BD NOS (and Generalized Anxiety Disorder).

As has been pointed out in this thread it is very likely that your pdoc is giving it some time so she can give you a more specific and all-encompassing dx. Another example (and I am not at all suggesting that this is the case with you; it is only one example) would be the fine line between BD1 and Schizoaffective Disorder. They can sometimes look alike; therefore, it takes time for a pdoc to decide which dx is the prominent dx.

I strongly suggest that you share your concerns with your pdoc. Tell her that you are concerned that the dx of BD NOS doesn't acknowledge the extreme discomfort you are feeling from the symptoms you have. Hopefully, she will explain her plan to you, and her reasoning for diagnosing you the way she has.

Lastly, please try not to ruminate over the dx you have right now. They can change over time, and they can change - at least somewhat - with different pdocs...although more commonly (from what I've experienced), a diagnosis fluctuates over months/years. Ideally, your pdoc will work with you frequently enough, and over enough time (usually a few months) before s/he firmly decides on which dx best fits your symptoms.
