Anytime I am excessively anxious or stressed, my body responds with a raging headache. 

After every breakup, I have had a severe headache, sometimes turning into a migraine. When I am in the middle of an anxiety-filled move, my body gives me a headache. Today when I have a lot on my plate and am trying to get loads of work done--headache. Nervous about a trip, flight, presentation, first day of work, test in graduate school--headache. 

My general anxiety is pretty well managed with therapy and medication, but the headaches are just something I have come to accept.
