Bipolar 1 is not worse than bipolar 2, only that it has a broader spectrum of expression than bipolar 2. People with bipolar 1 can experience manic episodes, hypomanic episodes, depressive episodes, and mixed episodes. Persons with bipolar 2 mostly experience hypomanic episodes and depressive episodes.
In both cases, the patient experiences maniac episodes characterized by elevated mood, which manifests in the form of euphoria or irritability. They may also experience hyperactivity, increased energy, inflated self-image, and excessive spending. In severe manic episodes, the person may start grandiose, unrealistic projects. The patient may also behave strangely and become delusional. Depressive episodes are very similar to clinical depression with low energy levels, foul mood, feelings of worthlessness or guilt, loss of pleasure, and suicidal ideation.
The main difference is that patients with bipolar 1 experience manic episodes while those with bipolar 2 experience hypomanic episodes. However, both sets of patients experience depressive episodes. What's more, depressive episodes in bipolar 2 are more prolonged than in bipolar 1.
