85/43 Blood pressure, feeling lightheaded, dizzy, and weak. Help?

I'm a 17 year old girl. Last night I started feeling ill. I was getting lightheaded and had a hard time moving around. I figured it was probably due to lack of sleep (gotta love college life). But I slept in for a while and woke up feeling worse. My hands are shaky, I feel like my head is in a cloud, I get lightheaded every time I get up to do something.
I've never had problems with my blood pressure. In fact, every time I go to the doctor they've always told me how perfect it is. I looked up a blood pressure chart and it said mine right now (85/43) is a little low.
What could be the cause of this and how do I fix it?
I've been eating and drinking and getting plenty of exercise!

You may be dehydrated. But no one on here knows for sure. Go to a doctor!

3 years ago, I was diagnosed - hypertension with a reading of 160/100. I used to feel dizzy a lot, my legs had awful cramps, and levels were very low in my potassium, causing my fingers and toes to always cramp together. One day I started to feel really faint while I was driving with my daughter in the back seat and I passed out, hitting 3 cars and ending up in a ditch. That moment,I knew I had to do something because my meds weren't working. I heard about this diet from a friend and thought I'd give it a shot. The results have been remarkable. In just 21 days, I honestly can't remember feeling this good, my blood pressure went from 175/110 to 125/70.
