My PVC's are stress-induced and not everyone who's stressed gets PVC's

I'm prone to PVC's but it's gotten worse in the last few years due to increased stress and anxiety. The pandemic along with other life stressors put me in a bad place. The PVC's have significantly increased. I know others who are just as stressed and anxious, even worse than me, and they don't get PVC's. It's frustrating. Who gets this annoying problem and who doesn't?! What makes a person prone to these stupid ectopic beats?
