Hello and welcome to HCM.
Thank you for your query.
It does sound like a possible hypoglycemic episode. This is a result of
low blood sugar levels, and is accompanied with sweating, confusion, a general feeling of
lethargy, altered consciousness and can even result in serious complications like
coma and death.
Please do not ignore this, get your blood sugar levels checked, and avoid going for long duration's without food. Eat small and healthy portions of food. Also, a consultation with a doctor would be best at the moment.
In the future if you feel the same way again, make sure to have a bite of chocolate of a glass of water with sugar dissolved in it immediately.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
Best wishes.
