1. Racing/intrusive thoughts with paranoid delusions (associated with mixed mania)
2. Severe anxiety and agitation
3. Crippling depression, with isolation, low self-worth, and crying spells
4. Manic impulsivity and self-destructive actions
5. Irritability with anger
6. Insomnia/lack of sleep (causes a lot of the above).

More, but those are 6 that come to mind as really bad. It's hard to put them in order completely, since sometimes one leads to another.
