Sudden Rush of Dread?

Idk if it was that 1 singular sip of redbull I had today, but for some reason my anxiety is high but like low-key. Like there's a sudden feeling of Dread running rampant within me, like as if something bad is gonna happen or like I'm trouble when I haven't done anything. 

Like am I gonna die in a crash tonight? Is my boyfriend gonna leave me? Is my heart gonna shut down? Is someone I know gonna die? WHY DO I FEEL ANXIOUS TODAY????

And I highly doubt it's that tiny amount of caffeine I got, I've been able to drink redbull no problem before I doubt it's gonna make me react this way when it wouldn't before. so idk what's up ://///
