Anxiety over migraine symptoms

More about migraines…I very rarely get migraine headaches, like once every several years, and I never think or worry about them at all….until this week. I got three migraine headaches in a row. Each morning for the past three days I woke up with a visual aura which is the precursor to the headache, followed by development of the headache.

Now I’m so anxious that I’ll wake up with one tomorrow morning that I can’t fall asleep (normally, I have no trouble falling asleep). I have thoughts like, Oh no, what if it happens again? Why is this happening so much? I’m tired but I can’t fall asleep because I’m so anxious. I feel so terrible with this anxiety. And I’m constantly watching my vision to monitor for the presence of a visual aura.
I’m just not sure how to deal with this situation.

C: Three migraine headaches in a row this week
T: I’m so afraid I’ll get the visual aura again. That would be so terrible to get another migraine headache.
F: Anxious
A: Heart rate goes up, constantly scanning for new visual auras, I get distracted from my present life
R: I make myself miserable
