So, I'm not by any means an expert - I can only share my own experiences and what my p-doc has told me.

After seeing my current (and very experienced) therapist for 5 years, and my excellent pdoc for almost 2 years, they both finally diagnosed me having bipolar. The complication with my diagnosis, and what made it so difficult to identify is that I've never really experienced a true manic or even hypomanic state in the sense of feeling really good as you're describing. I've always gone from a deep depression to a few days or even just hours of "normal" to a mixed state where I am severely anxious. So, I presented as having anxiety, not bipolar, and for the longest time, both my pdoc and t did not feel that I had bipolar...until my latest episode. My latest mixed state episode was so much more severe than anything I've experienced. I was agitated, anxious, paranoid, suicidal, irritable. I felt scattered, I couldn't focus on anything. I wasn't sleeping, but also wasn't tired. I wasn't eating, and wasn't hungry. When I put it all together and shared it with my T, she asked me to make an appointment with my pdoc asap. My pdoc, after an hour long appointment said that he things I have bipolar disorder. I just don't present in the "usual manner."

As my pdoc and I talked, he said that the reality is that very rarely does a person present as a textbook case. You have to look at the cycle of behaviors and look at the big picture of all the symptoms put together - both the highs and the lows and how they change over time.

For me, the biggest indicator that my pdoc's diagnosis of bipolar was how normal, how leveled out I started feeling once he got me on the proper medications.

So - all that to say, a lot of what you're describing does sound hypomanic. I would definitely talk to your pdoc about it. Also, my experience has been that the longer you go untreated, the more severe the highs and lows become.
