Yesterday was Great \ Today Horrid

Yesterday my pain was actually manageable and me and my mom were able to have a decent day.  I was so happy.  It was so nice for a change.  Last night my headache started.
I woke up with slight headache but within 45 minutes I was in full blown attack. My ears felt infected, my head hurts so bad and my eyes are about to pop out.  I hate this disease.  
Tomorrow I'm suppose to go to opening day at Rangers Game and tailgate and go to game with 40 others.  Once again I am going to cancel out.  :( I may just go and be miserable. 
Dear God why is this happening?  Please Help Me!
