This is, at least for me, an apt description about the difference between mania and hypomania. With full-blown mania, I tend to lack insight in a big way - sometimes psychotic features are present...sometimes not. When fully manic, I've found myself lying to others and having urges to shoplift while engaging in over-the-top shopping sprees. Normally, I am an honest person, never shoplift, and actually dislike shopping itself. My appetite completely disappears but that may be related to my ED. Random songs constantly run through my head (although this happens with hypomania, too). My thoughts race like wildfire and somehow I even get to where I am thinking of several things at the same time. Think of the diagram of the atom...it's like that during fully blown mania with the thoughts. Of course, I talk, talk, talk - and I generally am an introvert. I literally feel like the world is my "personal playground." I do not get physically aggressive but experience hypersexuality. I could go on but hopefully this is helpful description-wise.
