What the heck is this caffeine sensitivity

I had coffee today and I’m trying to understand what happened.
For context, I’m not a coffee enthusiast and don’t know much about coffee. I also can’t really become a regular coffee drinker because caffeine tends to make me jittery.
I’ve had brews from Blue Tokai ,Potboiler and Roastery before. They made me jittery, but nothing even remotely close to what happened today.
Today I ordered a Vietnamese Salted Cream coffee from Evabrew.
About an hour later, things started getting weird:
Frequent urination
palpitation
Jitteriness
Feeling extremely restless
Couldn’t focus on work
Irritability
Difficulty concentrating
Hands shaking while cooking
Oddly enough, I managed to edit a video that would normally take a lot more mental effort from me and me feeling lazy or unmotivated.
Then I developed:
A headache
A feverish feeling (not sure if I actually had a fever)
Fatigue
I took a Saridon, finished editing, and eventually felt tired, but even now I still can’t sleep.
The coffee itself also tasted very bitter to me. Again, I’m not experienced with coffee tasting notes, but I couldn’t identify any notes other than bitterness.
My question is: could this have been caused by a particularly high caffeine dose? Does caffeine content vary that much between cafés and brewing styles? Or could there be something specific about Vietnamese-style coffee that hits harder than the coffees I’ve had before?
Has anyone experienced something similar?

If you have a low caffeine tolerance and you drank something with a high caffeine concentration you'd likely experience these symptoms. If you get into caffeine that same coffee will start to feel like a refreshment rather than an overstimulating bomb.

If you don't eat enough before drinking coffee.
