Judith Orloff wrote a book called "The Empath's survival guide: Life strategies for sensitive people"
In her book she has a test to see if you are or not, here is a short version of it:
QUIZ: AM I AN EMPATH?
Ask yourself:
Have I been labeled as “too emotional†or overly sensitive?
If a friend is distraught, do I start feeling it too?
Are my feelings easily hurt?
Am I emotionally drained by crowds, require time alone to revive?
Do my nerves get jarred by noise, smells, or excessive talk?
Do I prefer taking my own car places so that I can leave when I please?
Do I overeat to cope with emotional stress?
Am I afraid of becoming engulfed by intimate relationships?
If you answer “yes†to 1-3 of these questions, you’re at least part empath. Responding “yes†to more than 3 indicates that you’ve found your emotional type.
Recognizing that you’re an empath is the first step in taking charge of your emotions instead of constantly drowning in them. Staying on top of empathy will improve your self-care and relationships.
Here's the website I got it from:
How to Find Out Your Emotional Type - Judith Orloff MD
She also has a test in the book to know what type of empath you are: emotional, physical or intuitive. And then heyoka empaths have all of the 'abilities'.
