I Do Not Drink Coffee. Nor Any Caffeine. I Do

i do not drink coffee. nor any caffeine. i do have decaf green tea and decaf black tea. caffeine from normal tea makes me panic so does coffee. sometimes if i steep my decaf black tea or my decaf green tea for 5 mins or more i get panic attacks. what does this mean. i hear green tea is safe but normal green tea is a no no for me herbal caffeine free tea is fine.
