Headache day 3

So I woke up Tuesday morning with a headache.  Thought it might be sinus' so I used my netti pot.  Nope headache still there.  I took some of my Excedrin migraine pills before I went to bed that night hoping it would go away while I slept.  No such luck, tried multiple things yesterday and it still didn't go away.  Woke up this morning with it worse then ever. I think it may be tension because while I am looking forward to the kidney walk on saturday a part of me is dreading it.  I'm afraid of how I will handle doing this without David.  This was his thing and I want him to be proud of me and I feel like I am putting more pressure on myself for some reason.  I think I am going to go lay down in bed with the curtains closed and see if that helps. =(
