That's OK. Just apply the Anchor when you are re-living the event in your mind because you know or imagined you felt good at the time. Some people find it difficult to express emotion - maybe they have been taught to suppress it, keep a stiff upper lip, don't cry, don't be vulnerable, etc. Just make it OK to re-live the event without the emotion and gradually the emotion will start coming through for you.
