Mental illness symptoms can include anxiety and unusual behavior. Early detection is important to avoid relapses. Medication is essential, especially for relapse prevention. Agitation or behavior may require evaluation for admission. Reduce stress, avoid discussing delusions, and avoid confrontation or criticism.
