Addicted?

Saw this in an article recently:

Addicted to that feel-good feeling?

Love something a little too much? You might want to start worrying, says Frederick, if it's helping you mask or avoid underlying feelings, issues, anxiety or discomfort -- "for example," he says, "being overly active, or addicted to working out, as a means to regulate one's anxiety."

Um, is that really considered a problem?!?
