I believe Shirley Stevens has a mental disorder which is called Bipolar Manic.
Bipolar Disorder is a mental disorder that causes depression. It could result in the fluctuation of emotions/ mood. A person with this condition may sometimes feel sad and sometimes feel happy. Bipolar Manic is a phase of Bipolar which is usually on the high side. It is also called Manic episodes. When a person goes through the Manic episode, he/she experiences a high feeling like a drive to achieve something beyond the usual. It is an optimistic feeling that you can do anything. A manic episode can be detrimental, especially when a person with it does not get the result of his/her feelings or wishes. The symptoms of Bipolar Manic include paying attention to irrelevant things, lack of sleep, the extreme urge to keep talking, involving in goal-driven activities, etc. Bipolar Manic can be treated with enough therapies and medications like anti-depressant.
