The 5 of Pentacles is an assignment-number card, and is about letting go of your securities. Pentacles element Earth (also) represents material posessions, so this card is about letting go of (some of) your worldly assets.
Don't look back, and don't get depressed over what you've lost. Things may seem a little barren right now, but help is on the way.
Despite losing something, you gained something as well; freedom from ties.
You're too afraid of losing your securities and thus setting yourself free.
