If you're using the term "maniac" in a colloquial sense, it may refer to someone who is extremely enthusiastic or passionate about something. Being interested in something to a high degree can be a positive trait as it shows dedication and commitment.
However, if you meant "maniac" in a more negative sense, like being obsessed with something to an unhealthy or dangerous extent, it could be a cause for concern. It's essential to be mindful of our interests and ensure they are not harming ourselves or others physically or emotionally.
If you have any concerns about your interests or behavior, it's a good idea to talk to a mental health professional or a counselor. They can help you understand your feelings and behaviors better and provide guidance if needed. Remember, seeking help is a sign of strength and self-awareness.
