Anxiety or asthma: I see no medical history in your profile. This sure sounds like anxiety induced asthma. I would advise rest. Meditation. And beginning to work on the body mind connection.

Costochondritis?: Chest pain often is associated with cardiac disease. However musculoskeletal injury or inflammation involving rib (costochondritis) or muscle can cause pain. Gastroesophageal reflux is probably the most common cause of chest pain. Should consult physician for further evaluation and perhaps testing.
