20 Concerns Associated With Dysthymia
2. Undiagnosed Anxiety Disorders

Some patients with depression may also display signs of anxiety disorders. Some symptoms include an overactive fight or flight response leading to a severe sense of panic, dread, distress, restlessness, apprehension, palpitations, chest pain, sweating, nausea, vomiting, diarrhea, headache, muscle tension, and insomnia. If left undiagnosed, the depression could worsen, leading to dysthymia. The mood and behavior issues would further impact the individual to a state in which functioning on a day-to-day basis becomes difficult.
