If you have an adjustment disorder it's probably likely that those changes are not going to be as easy or as fun as they might be for other people. An adjustment disorder occurs when an individual stresses kind of exceed their resources for coping and Nikki Nance, a professor of psychology at this college in Florida says that your reaction with this disorder kind of becomes disproportionate to the event you're reacting to. In people who are uncertain 75% of people mispredict when bad things are going to happen so this uncertainty bias trains our brain to expect the worst.
