Absolutely... anxiety can cause you to experience almost any symptom you can imagine.

What is troubling you?

thats the thing... theres nothing troubling me at all.... thats why i dont understand it

strange.

do you smoke?
how is your sleeping cycle?
btw, can you describe the seizures in more detail?

I don't smoke at all, never have done.
My sleeping was normal for the first 5 ish months even though i was very very tired, then every time I slept it was a very deep sleep and now I'm having difficulty sleeping.
The first seizure, I got up went to the kitchen, got really, really dizzy and got spots in front of my eyes. I held onto the fridge and my knees started shaking then it cleared up. The second time it happened I had fallen asleep on the sofa then stood up and got dizzy with the black spots then collapsed on the floor and came too a minute or two later. The third time I got dizzy, had the black spots then my mum told me I fell back onto the sofa, my eyes rolled back and I was shaking. The last time my boyfriend noticed me shaking in my sleep. I get the black spots infront of my eyes pretty much all the time but the usually clear up by itself but sometimes it gets worse...
Oh and also when I was seeing the doctor yesterday he was listening to my chest, asked me to take deep breaths and at about the second one I became really really dizzy and was like that for about 20 minutes.

Hmm... ok, what you're describing is sounds more physiological than emotional or psychological, altho the emotional stuff can create the physiological symptoms too.

I have very low blood pressure, and when i do not eat regularly (and have not had regular sleep exercise) something similar happens to me. I can barely stay upright. Especially after lunch, i HAVE to lay down otherwise i feel like i'm about to collapse.

How is your blood pressure?

For me I know that it's connected to the low blood pressure. Drinking lots of fluids (water) helps to keep the BP higher, but it also makes a big difference to eat more often and smaller meals.

When I eat greasy food, it happens more... when I eat for example a salad, I do not feel like I am going to faint. Someone explained this phenomenon to me once as the blood descending into the stomach for digestion. Given that my BP is already low, it makes sense that the head is not receiving enough blood.

Does any of this sound familiar or am I way off?

I've had my blood pressure checked loads of times and every time it comes back normal.
I have all the doctors confused because even when I have an infection and the do blood tests, the come back normal too. You'd expect the white cell count to be higher, but its normal.
I have even had two ECG's done, they both came back normal too.
The only slight answer I have gotten so far is anxiety, which I doubt it is.

if dr.s are confused then it might be that your immune system is acting the opposite of normal. ecgs might be normal but it seems your brain is sending mixed signals to your immune system.
