7. An exaggerated opinion about oneself
In a maniac episode, patients with bipolar disorder have delusions of grandeur or at least an exaggerated opinion of themselves. They feel capable of doing almost anything and may sometimes undergo risky behaviour just because they feel they are able. They often use exaggeration and lie to make their accounts and feats more interesting for their listeners and sometimes genuinely believe their own lies.
These patients truly believe they are important people or have important friends. Thus, they are often uncontrolled in shops and spend a lot of money believing they can pay their debts afterwards.
