Bipolar Disorder Support Group
Bipolar disorder is not just a single disorder, but a category of mood disorders marked by periods of abnormally high energy and euphoria, often accompanied by bouts of clinical depression. This is the place to talk about your experience with bipolar disorder, learn from others' experiences, and find support.

I would ask for a referral to a psychiatrist .... They can do a good evaluation ... Big hug....xo
Maybe write down a list of why u believe u might be bipolar so when your there u can give a clear case why u need reffering to a psych dr.
Good luck.
I'd go in saying that you have some problems and describe what the symptoms are and how they affect you. You can always add I wonder if it is bipolar?
The reason being is that there are so many things that look like bipolar that really most people aren't competent to self diagnose or even get close. For example, it might be Borderline Personality Disorder or one of the many other disorders less well known and so never googled.
You can look on your Health Insurance website to see what Pdocs (psychiatrists) are in your local network.
Going to a Family Dr. or PCP for Mental Health needs puts you at the risk of them putting you on whatever popular psych med the local drug rep is hawking this month and it can be something that might cause you to be worse. They don't know what meds are needed to treat BiPolar or similar Mood Disorders.
You may need a referral to see a pdoc, but dont let your gp diagnosis you, it isnt their field.
Fish has some very good points made as well.
Best wishes in finding the answers you need to put you on the road to stability.
Have a good Monday.
