hi, thanks for writing..
bipolar disorder also runs in families..in bipolar disorder there are two main types.in bipolar type 1 there alternating episodes of mania with
depression and it is of more severity.
in bipolar type 2 there are episodes of depression with
hypomania alternately..this is some what less severe but causes lot of problems..
what you are describing is rapidly changing mood change that can be ultra rapid cycling bipolar disorder, but there many things to be asked before a diagnosis can be made..
there are high chances of you having bipolar disorder, so you shud
consult a psychiatrist and tell your feelings and symptoms, also talk about rapidly changing mood without a reason..
there are drugs which are different for treatment of both types of
bipolar disorders, so making a diagnosis will be very helpful,. that happens only by visiting a psychiatrist..
drugs will help you..so you shud seek treatment..
i hope this advice will be helpful to you..best of luck..
