I created a flow chart to illustrate possible ways to deal with the feeling of frustration.
Wikipedia: "In psychology, frustration is a common emotional response to opposition [or unexpected obstacles to goal fulfillment], related to anger, annoyance, and disappointment. Frustration arises from the perceived resistance to the fulfillment of an individual's will or goal and is likely to increase when a will or goal is denied or blocked." (Wikipedia article).
Is the following chart helpful? Is there anything which should be added or changed?
