Thanks for your query. Based on your history-the various possibilities include hypoglycemic attack, hypotension
(low blood pressure) or panic attack
state). Considering that after food you felt better, my advise would be not to skip meals particularly breakfast. Panic attacks can also manifest this way though unless these attacks repeat themself i would not suggest you undergo a psychiatric evaluation. I suggest that you check your blood pressure on three consecutive days, check your blood glucose
fasting and after food so that we get better clarity into your symptoms. There is nothing to worry. Wish you good health.
