There is an important distinguishing factor between being dx with unipolar depression and bipolar, and it comes down to treatment through medication, and also other management tools, not to mention the actual symptoms. Many people here have been misdiagnosed with unipolar depression for significant amounts of time and did not have much improvement until a correct dx of bipolar was made. I've read that here and other places many many times. If you don't know what you are treating, how do you treat it in the best optimal way? If I have diabetes or hypoglycemia I hope I would get a correct diagnosis. Breast cancer, colon cancer, while both are cancer treatment may be different and mental illnesses are not that much different.

When you are talking to your dr about this, don't be afraid to speak up and say.. I just do not think this is depression. Make a list of symptoms an hand it to them. Also make sure your dr considers physical reasons as well, thyroid, and physical symptoms. You would be surprised how many physical illnesses cause psychological illness. Dr's from my experience seem quick to jump the gun on mental illness without considering all possible cause.

Good luck I hope you find some answers.
