Here are some possible interpretations:
1. The Feeling of Fear: This could mean simply experiencing the emotion of fear, without any other emotions accompanying it. This is highly unlikely as fear is often intertwined with other emotions like anxiety, anger, or sadness.
2. Fear as the Dominant Emotion: This could mean that fear is the most prominent feeling, overshadowing any other emotions. In this case, fear would be the primary motivator and influence on someone's thoughts and actions.
3. Fear as the Only Motivator: This could mean that fear is the only force driving a person's behavior, leading to paralysis or inaction.
4. A Metaphorical Expression: "Only fear" could be used figuratively to describe a situation where fear is the only obstacle preventing someone from taking action or achieving something.
