Someone who cares about you when no one else will is a blessing that should be appreciated
An empathic person naturally feels the pain that another person is feeling. He or she sees themselves in that situation the person is in and feels sympathy. Many times I've seen people go through incredibly painful experiences in their lives, without anyone's help or assistance, or at the least - someone's sympathy.
Even people very close to the person, family included, might know and be aware of their woes, but are unable to empathise and act or speak to comfort appropriately. It takes someone with that ability to perceive their pain and help them heal.
People talk and people listen, but very few care enough to help. During bad times, finding someone who cares about you when no one else will is one of the most healing and uplifting experiences ever; but so rare that it requires appreciation.
Identify and appreciate people like that in your life. Don't turn a blind eye to those that empathise; that care when no-one else does, because it could lead to a very satisfying and meaningful relationship, with profound levels of loyalty.
