There is no evidence that CH, as a specific disorder, induces emotional distress, etc. There is a much larger body of literature about the impact of chronic illnesses, broadly defined, on the development of anxiety disorders, depression, and so on.
There is a limited literature suggesting that certain personality types are more sensitive to pain, feelings of powerlessness, and generalized emotional responses which make the underlying disorder more troublesome.
I'm going to throw a couple of articles at you--not as a diagnosis of your situation--but as samples of the kinds of research which link physical disorders to anxiety, etc.
Last, a link to a form of cognitive counseling which you might try on your own which can, with some self-discipline/practice, modify your emotional reactions to the CH. Cognitive therapies have been well researched and are quite potent but you may wish to consider consulting a therapist if this approach is of interest.

Report of a study (from MEDSCAPE.COM):"Patients With Anxiety Disorders More Sensitive to Bodily Changes"
Sept 16 - Patients who have anxiety disorders appear to be more sensitive to bodily changes, which in turn suggests that the perception of panic attacks is reflective of central rather than peripheral responses, according to the results of a study published in the September issue of the Archives of General Psychiatry.
"Physiologic responses of patients with anxiety disorders to everyday events are poorly understood," Dr. Rudolf Hoehn-Saric and colleagues from the Johns Hopkins Medical Institutions, Baltimore, write. They compared self-reports and physiologic recordings in 26 patients with panic disorder, 40 patients with generalized anxiety disorder, and 24 nonanxious controls during daily activities.
The subjects underwent four 6-hour recording sessions during daily activities while wearing an ambulatory monitoring device. The team collected physiologic and subjective data that were recorded every 30 minutes and during subject-signaled periods of increased anxiety, tension, or panic attacks. Primary outcome measures included recordings of heart inter-beat intervals, skin conductance levels, respirations, motion, and ratings of subjective somatic symptoms and tension or anxiety.
Compared with controls, patients with anxiety disorders rated higher on psychic and somatic anxiety symptoms. Patients with anxiety disorders also rated themselves higher on disability scales and on sensitivity to body sensations. Both patients with panic disorder and those with generalized anxiety disorder experienced diminished autonomic flexibility and less precise perception of bodily states.
Patients with panic disorder had a heightened sensitivity to body sensations compared with generalized anxiety disorder patients. Autonomic arousal levels were slightly higher in patients with panic disorder, and this manifested itself in faster heart rates throughout the day.
"These findings suggest that, after having experienced anxiety attacks that are associated with strong bodily changes, patients become sensitized to such changes and may experience physiological symptoms of panic attacks..." [In effect, their bodies are acting as if there was a threatening condition even when this was not the case.]
The investigators note that the diminished autonomic flexibility found in both panic disorder and generalized anxiety disorder patients may result from dysfunctional information processing during heightened anxiety that does not discriminate between anxiety-related and neutral stimuli.
"It is important to measure physiological responses and not rely on verbal reports," Dr. Hoehn-Saric added. "A demonstration that physiological responses during anxiety attacks are milder than perceived can be reassuring to patients," he said. "However, the long-term effect of diminished physiological flexibility is unknown."

________________________________________________
Imagine a person who is afraid of, for example, dogs and can experience an anxiety attack by thinking about meeting a dog or even seeing a picture of a dog. (Or, replace "dog" with your own feared thing/experience.) The anxiety is NOT being caused by a real life experience, in this situation (the thought or picture). The mental and body reactions which we call "anxiety" are a kind of habit response which are very real in their effects, however. Anxiety produces mind and body reactions which are measurable and have a real impact on how we function (and even on long term health of the body).
The anxiety becomes an automatic response, beyond direct control of will. With this development, the person has experiences (anxiety) which are confusing or misleading--they cannot separate the real life threat from their body's automatic ("I'm in danger!") reactions. When dealing with cluster, for example, the effect of this anxiety reaction (and this is true for depression also) is that the person has increased sensitivity and reduced tolerance for pain; their sense of suffering is elevated and the capacity for effective self-treatment is reduced.
Medication can dampen the experience of anxiety but it does not unlink the reaction from the underlying thoughts or misinterpretation about the situation. ("I'm in danger"; "this will never end"; "I can' bear the pain", etc.) Cognitive therapies have been very effective (especially when combined with short term meds use) in teaching folks how to break this link.

The contribution of pain-related anxiety to disability from headache.Nash JM, Williams DM, Nicholson R, Trask PC.
Centers for Behavioral and Preventive Medicine, Brown Medical School/The Miriam Hospital, Providence, Rhode Island, USA. Justin_Nash@brown.edu
Disability associated with headache cannot be fully accounted for by pain intensity and headache frequency. As such, a variety of cognitive and affective factors have been identified to help explain headache-related disability beyond that accounted for by pain levels. Pain-related anxiety, a multidimensional construct, also has been found to contribute to disability in headache sufferers. What is not known is whether pain-related anxiety is unique in contributing to disability beyond the role of headache-specific cognitive factors and emotional distress. The present study examines the influence of pain-related anxiety on disability, after controlling for pain, cognitive (self-efficacy and locus of control), and affective factors (emotional distress) in a sample of 96 primary headache sufferers. Pain, headache-related control beliefs, and emotional distress accounted for 32%, with locus of control related to health care professionals contributing unique variance.
IN THE FULL MODEL, WITH THE ADDITION OF PAIN-RELATED ANXIETY, ONLY PAIN-RELATED ANXIETY WAS A UNIQUE PREDICTOR OF DISABILITY. THESE FINDINGS SUGGEST THAT PAIN-RELATED ANXIETY MAY HAVE A UNIQUE AND IMPORTANT ROLE IN CONTRIBUTING TO DISABILITY IN HEADACHE SUFFERERS.
