Fear is an emotional response to danger. Anxiety is a physiological response that often arises out of and in proportion to the actual threat or danger involved. In the case of multichannel marketing, fear and anxiety can result from a sense that your advertising doesn't appear to be working any longer. I can't track the response. I have to immediately cut my ad budget back. I need to limit ordering choices. I need to change agencies. What should I do? I may get fired.
