Bipolar: Manic depression is a mood disorder that presents with extreme highs & lows, with at least few weeks of manic phases (abnormally elevated mood & energy level) alternating with few or more weeks of depressed phases (sad, guilty, hopeless/helpless, changes in sleep/appetite/energy level). Any phase can be severe enough to experience delusions or hallucinations.

In depression it is helpless, hopeless, weight gain or loss, too much sleep or insomnia & no pleasure out of any thing. Other side extreme ecstasy state spending too much, too fast, partying whole night- erratic behavior. Please read depression- http://doctorrajput.Com thanks.
