The term "more bleeding heart" refers to someone who is excessively or overly sympathetic or caring. The antonyms for this phrase would be individuals who lack compassion, are unsympathetic, or indifferent to the plight of others. Some possible antonyms might include callous, unfeeling, hard-hearted, cold, unsympathetic, and insensitive. Although having a compassionate and empathetic heart is generally seen as a positive trait, being excessively empathetic can also lead to burnout and compassion fatigue, making it important to strike a balance between empathy and self-care. By learning to be less of a "bleeding heart" and developing a more balanced approach to empathy, one can become a more effective and sustainable caregiver or helper.
