remember all this I, II business are labels. Not only, doctors attribute them differently. they are based on DSM "symptom specification" but the DSM is only a guide. ppl do not fit neatly in boxes. many of us have mixed states... the classical DSM def of a mixed state is very restrictive, and such occurrences are clearly more rare, but more recently the literature is identifying mixed states which are more depressive or more manic, but with some symptoms of each... not necessarily at a full manic level. anxiety is more associated with depression. however it is a more "activated" manifestation, and high anxiety can look manic.
