Hang in there. Your brain needs a bit more healing.

Funny you mentioned this, I just started working out again. I've had to take a hiatus from exercise for some 9 years, as any strenuous activity seemed to trigger my migraines. Then, for the past couple months, the migraines mysteriously went away. So, I started training again (I practice martial arts). Good, hard workouts, sometimes twice a day!

Point is, give yourself whatever rest your brain needs, and understand that it need not be forever. 9 years is not a short time, but it is not forever.
