I does sound a lot like your blood pressure just dropped - did you say you had been sleeping just a while before? Blood pressure is a lot lower during sleep, if you basically woke up groggy and dragged yourself to the steets, the sudden change of position from lying down sleeping to walking might have caused insufficient oxygen to rise to your brain. Similar to what happens due to orthostatic hypotension. You also said you'd been eating poorly, you could be hypoglycemic. The symptoms are those of a typical collapse, sudden weakness, dizziness, loss of consciousness for a short while and then an onset of nausea and funny noises in your ears. I'd vote more on the hypoglicemia hypothesis since you felt really weak afterwards.
The only thing that worries me is the "heartburn" thing. I have fainted before exactly like that (and thanks to my underweight body, I experience near-fainting episodes a lot) but never got prolongued symptoms such as chest pain. Do you know anything about the current status of your health? How long since you've gotten your blood tested, a heart rythm exam...? I'd seek a doctor a.s.a.p. If you can't, at least go to a pharmacy to get your blood pressure and glycemia tested (it's for free in France, I think. At most 50 cents each test).
