Caffeine makes me sick?

Anyone else have a caffeine sensitivity? Is yours like properly diagnosed or did you just discover it on your own?

I don't drink coffee, but even caffeinated tea or soda will make me feel nauseous and lightheaded. It's kind of how I'd feel if I were really sleep deprived. I generally avoid caffeine but I had a bubble tea today (wasn't sure if it was actual tea or just juice so I took a chance and tried it) and now I feel sick the way I always do after caffeine! But everything I can find online is specifically about coffee making you sick, or says that caffeine sensitivity causes jitters, palpitations and such. I don't get those symptoms, it doesn't give me any kind of energy boost, just makes me feel like I could puke and makes me want to lie down. Anyone know anything about this?
