People who purposely try to trigger someone's fears or phobias are often referred to as "fearmongers," "provocateurs," or "intentional tormentors." Their behavior can be harmful and insensitive, as it deliberately targets someone's vulnerabilities to cause distress or anxiety.
It's essential to recognize that engaging in such behavior is not acceptable and can have significant negative consequences for the person being targeted. If you find yourself dealing with someone who engages in fearmongering or intentionally triggers your fears or phobias, it's crucial to set boundaries and seek support if needed. Consider talking to someone you trust about the situation, and if the behavior persists, consider removing yourself from that person's presence or seeking professional help to cope with the emotional impact.
