Learn to distinguish between positive stress and toxic worry. Positive stress can give you the energy you need to get the job done. Toxic worry only drags you down, making it hard to achieve even small tasks. Do a reality check. Find out if your worry has any basis in fact.
Toxic worry can distort the real situation.
Check to make sure things are really as bad as they seem. Even when there is an actual problem, it may be easier to solve than you think. Talk with friends or colleagues you trust. They can help you see things differently. Connect with those you know will reassure you, not those who might exaggerate your concerns.
