Often when someone comes to you and wants to vent, it's so tempting to start giving advice. But if you allow the person just to let the feelings out, and then at another time come back with advice or comments, that person would experience a deeper healing.
We need to deprogram ourselves. I know for sure that you can't give what you don't have. If you allow yourself to be depleted to the point where your emotional and spiritual tank is empty and you're running on fumes of habit, everybody loses. Especially you.
