In the dark. . .

Five days in the dark.  I so need this migraine to go away.  Doing school work with my head hurting is not so good.  Thankfully I am caught up.  The picture is pretty descriptive, however mine feels as though someone has used a can opener on the top of my head and is pushing the lid portion down.  I haven't had one hold on this long for almost a year.  Wish I knew what caused them to come and what is the difference between the ones that are here just for a day and the ones that stay day after day.  My children are being oh so quiet.  I am blessed, but oh how I hurt.
