Can migraines cause diarrhea, jitters and no energy and just make you feel blah and horrible?

Sure: Migraines can certainly have a tremendous impact on your quality of life. The pain and fear of recurrence can lead to anxiety and depression, which can be responsible for a number of body symptoms (psychosomatic). Conversely, hormonal imbalances can cause migraines, fatigue, and some of the other symptoms you have described. The trick to feeling better is determining the root cause.
