You tend to help others when you are inj pain. Reason is, “EMPATHY”… researches have proven that all human beings experience empathy. There are mirror neurons in brain which reflect other person’s feelings on self. So no one can see other person in pain. So your helping nature might have originated from your pain.
In the same way, when you are in pain, you will feel that other person is also in pain. If you are in danger, you will see world as a dangerous place.
The projection of pain brings bias and hides the reality. You can help other person only if you see reality, only if you see story intact, ie. objectively.
Best thing to do is, get over your pain first and then try to help other person.
