Based of my long research paper about BDWell BD 1 involves a full blown mania that lasts at least from a few days to god knows when while hypomania is a less severe version of mania and doesnt last that much . Mania often involves psychosis and hallucinations which dont occur during hypomania . Mania ' s excess energy and irritability is so extreme to the degree that the person can ' t carry out normal everyday functions ie of course if the person is not stabilized . Trust me , if you were manic you wouldve known bc it changes your whole life , flips it upside down , it ' s no longer you in control of anything , it ' s bipolar that takes full control of your life . And before you know it , youre in the ER shouting crazy stuff at everyone while they hold you down and insert an IV with tranquilizers to put you to sleep . I believe im not a doctor that you have BD 2 .
