Bipolar Disorder. The best is to meet a psychiatrist for an evaluation as there may be online surveys and checklist but these are just screening tools and can not replace a good evaluation.Lot of mood symptoms can be seen as depression or bipolar so please dont have a self diagnosis or what friends say get help asap.Its really helpful with new gen meds and treatment options. Good luck.
Bipolar. Moods swing to extremes, between episodes of depression lasting around few weeks & phases of mania lasting few weeks each. Milder forms are called bipolar type 2 or cyclothymia, more severe forms are accompanied with psychotic symptoms such as hearing voices or seeing things that are not there. Your mental health counselor can assess & give more definite diagnosis.
