While those who never had bipolar or done drugs may criticize Kara’s manic behaviors as if she were evil - and this, perhaps, according to Christian morality as they interpret it - anybody who has actually suffered from psychosis puts this to the lie and knows that psychotic behavior is not a moral issue, but a chemical imbalance. This can exacerbate their bipolar symptoms, leading to worse problems than if they were completely unmedicated and struggling only with the bipolar itself. It is true that many people who suffer from bipolar self-medicate impatient with prescription drugs, they might use drugs that have a more pronounced effect, such as meth or cocaine. This was offered as a counter-explanation to her shocking behavior.
In the case of Kara, it has been suggested that her behavior related to meth use or the use of other street drugs. Living with the aftereffect of a manic episode can be difficult to cope with. It alternates between depressions, long plateaus of a normal state, and sometimes a bright or manic effect, which may also be accompanied by psychosis, when the person acts in ways that do not resemble their character or values when properly medicated or in their right state of mind.
Like all mental illnesses, bipolar can be difficult to live with.
