I also agree that a concert will generally just bring out the happy side in someone, people can get excitable regardless.there's that happy-go-lucky mania where people start stealing cars for joy rides or other extremely dangerous risk-taking behaviors.
However because i am prone to mania, i do not generally need anti-depressants, during the times i DO need them it's a very fine balance between the medication helping my depression or just inducing a manic episode, that's when i tend to be more like this...
While i said that mania can make me an extrovert, at times even though i am extroverted i completely withdraw from those around me who might actually know what's going on with me, and shut down any connection where it is anything beyond superficial. So i guess i retain the introversion anyway.There is "high-strung" mania which is the bossy, controlling, vindictive, angry, delusions of grandeur kind of mania (I am untouchable, I am in control, if I see one speck of dirt I'll freak out)
And i don't think my "type" changes during highs or lows, I am and remain essentially an INFP, just either the healthy or unhealthy version of one.
