What Is Bipolar 2 ( Bipolar II) Disorder?

"Hypomanic Episodes-
The article What Is Hypomania? gives in-depth information about the upper end of the Bipolar 2 mood swings.

A few of the most common symptoms are:
Not needing a lot of sleep, but not being tired
Having more energy than usual
Risky behavior, such as reckless spending (see Controlling Spending in Mania and Hypomania for strategies that have helped our readers)
Grandiosity, pressured speech and/or racing thoughts.
One of the things that distinguishes Bipolar II from Bipolar I is that while the symptoms of hypomania can interfere with daily life, they don't cause "marked impairment in social or occupational functioning." Another difference is that there are no psychotic symptoms during hypomania. However, psychosis may appear during depressive episodes.
Depressive Episodes

The article What Is a Major Depressive Episode? gives the specific things a psychiatrist looks for in a patient to gauge the severity of depression.

Here are a few of the most common symptoms:
Insomnia or hypersomnia
Unexplained or uncontrollable crying
Severe fatigue
Loss of interest in things the patient enjoys during euthymia
Recurring thoughts of death or suicide "

I am not a doctor. Your behavior could a number of things. Could it be that you are just self-sabotaging because you are uncomfortable being in healthy relationships?

There are people who cheat and gamble who are not bipolar. Although you could be.
