Migraine Related or not

A few weeks ago I was, let's say "the old me." Highspirited, laughing, joking, smiling even. Obvious to my Fiance and my Children that I am "better" and we are "happy" again. Enjoying it as I was, I also clenched on to the though that at any given moment this would end and end it did and in a such a painful way.. It was not me in pain per say, I ache, but the pain in their eyes when I go down, the "here we go again" sigh when Mommy's head hurts. It's a bit more than my head this time, but what is it?? My blood pressure keeps dropping too low. I am dizzy and lightheaded. I am nauseous. I get so out of it that I can't comprehend whats going on around me. The pain in my head is not my usual head pain, and the dizziness is new. A New Symptom?? so, I saw the Doctor, Am I depressed? Tired? Can you define sick for me?(..again) I will say this, I am exhausted, the medications I take daily effect me tremendously, and depressed, I tend to be down some days, who isn't that suffers with this disease?! Low and behold, the doctor says this could be from my Topamax, however, does not taper me off..(uggh) I have bloodwork done, am scheduled for a CTScan, an Echo and also an ultrasound for my neck to check my arteries. I am hopeful that these will all be normal and maybe the medication is the problem. Maybe this is a new symptom. Yet again, maybe I have something else going on that has yet to be determined. Maybe, Maybe, Maybe... Unpredictable, I know, that's the life of a migraneur. That's my life.
