Headache!!

I've been suffering from severe headache since early this afternoon... Last nite i almost fell on the floor when i suddenly felt dizzy, i thought there was an earthquake.. I've been having hallucinations too, i feel as though some "bad air" needs to get out of my lungs and if i don't breathe them out, i would suffocate to death... i feel scared everytime i have that feeling.. my hubby told me that maybe i have brain tumors (lol) cause those are the symptoms Izzy of Grey's Anatomy had before she was diagnosed of the disease.. well, maybe after 5 years or so, I'd find this blog of mine true.. :(
