A medical exam may be warranted as there could be some indications of cervical disk problems which is out of my area to suggest possible treatments. Personally I know neck problems can interfere with the quality if not quantity of sleep and as a result can leave a "washed out" feeling. Now from my speciality of clinical psychology I would recommend an assessment of the life stressors you may be experiencing as they have a tendency to "collect" as physical tightness in the areas you describe.
