Mania is often similar to euphoria, which the patient enjoys but which can be dangerous as it causes a feeling of invulnerability that can lead to reckless behavior.

Depressive episodes can lead to drug abuse and suicide. Treatment is essential, but to get treatment, you first have to know what to look for and how to be sure you're really looking at a case of mental disorder.

This often ends in disaster: the affected party feels as if they're trapped, and may only give a response just to get you to let the issue go. The better approach is to let them have the space they need without judgment.
