This self-diagnostic/test contradicts some common (mistaken) beliefs about emotions and stress that you are likely to share with the majority of the population.
Stress is not a personality failing. Stress is simply the unavoidable physical response that everyone experiences from having lived through particular experiences. Perceptions can change, lessen, or increase the impacts.
Changes have multiple impacts on the physical structure and well-being of people. Independent of whether they like or dislike the changes.
If you have the experience, you are subject to the stress impact.
Stress impacts occur from positive experiences as well as negative ones. The fact that you value the event, does not alter the fact that the consequential effect has occurred.
How you deal with the impact is an issue of emotional skill and emotional resilience.
You can develop more skill in how you perceive the impact, to modify the impact and manage the effects on your physical system.
