Well, some say that bipolar disorder can get worse over time. A diagnosis of bipolar type two, by the book, does not include full blown mania, psychotic symptoms or mixed states (that were not induced by medication and/or drugs), so basically type two means, no mania, no psychosis or mixed states that the doctors know about (or find severe enough to change your diagnosis and perhaps some of your treatment), depression and hypo-mania gives you bipolar type two and if you get any of those other symptoms that type two does not include, you get labeled bipolar type 1 and maybe your treatment changes, lithium, antipsychotic and no doctor suggestion of possibly being off medication a year down the line.

It happens.
