Why do I stop feeling emotions and love occasionally?

Think of your emotions like waves. They sometimes are strong and forceful, hitting against the walls of our hearts and making the loud sound of thunder within us. At other times, they're gentle and moving back into the ocean, just a trickle against the softest parts of us. The water is always there; it just seems different depending on the tides just as love is always there but it, also, feels different depending on where we are and what we're doing. The love may not be less...it just isn't hitting us as strongly.
