Btw - of course I cannot and do not want to diagnose you anyhow - but when I was thinking that I might be bipolar, I discovered that closer would be borderline personality (fortunately it turned out that don't have it), as in my case the mood didn't change in a pattern: long depression, long high etc but the mood was changing even few times per day

Perhaps you could read about this as well, but as you've noticed - only your T/pdoc could give you the real diagnosis...
