Is being an empath the same as being highly sensitive?

Similar but different. Highly sensitive people (HSP) process sensory input deeply. Empaths feel others' emotions as if they're their own. You can be HSP without empathy, or empathic without HSP. Both require boundaries.

Why do empaths struggle in relationships?

Because they absorb their partner's emotions, they over-accommodate, and they attract people who need emotional labor. They become caretakers. Without boundaries, empathy becomes codependency.

How do empaths protect themselves?

Boundaries. You can be empathic and still say "I can't carry your emotions for you." Grounding practices (meditation, nature, alone time) help reset. And choosing emotionally healthy partners is essential—avoid narcissists who will drain your empathy.
