The 4 of Pentacles

The 4 of pentacles, or coins. Is the card of security, of the home, of delay, a physical obstacle, of hording.
When this card comes up in a reading, it's telling you that you need to let go of something, to give back to the universe.

What happens when you have nothing to give?
When you are drained physically, mentally, emotionally. When you are not part of something bigger then yourself. How do you handle it? What are you suppose to give when you have nothing to offer? When you are not a wife, not a mom, not needed, not wanted, not thought of. What do you do then? How can you give back when there is nothing for you to offer?
