Headache

I have had a headache for almost 12 days now.  Non-stop headache.  I have been nauseated, dizzy, lethargic and overall unwell.  I was taking Ibuprofen like it was candy.  But I stopped and am now just dealing with the pain.  I don't know if my emotional un-wellness is contributing to my physical un-wellness or the other way around.  I generally feel like crap on a stick.  I laid around the house all weekend.  I don't have the energy to clean my house....thank God for my hubby.....and I just don't feel like doing anything.  I am beginning to wonder if I have been bitten by something?
