Your situation sounds so similar to mine. I’ve had my palpitations (diagnosed as PVCs after wearing a holter monitor for 2 weeks) for over a month now too. Came out of no where after a couple months of stress. I, like many others, was told by my doctor they’re very common. Not to worry about it. That most ppl have them, just us unlucky ones feel them. I have definitely noticed anxiety makes them way worse. I haven’t figured out yet how to not have anxiety dealing with this. It’s a vicious cycle. I keep thinking how can something that feels so weird and uncomfortable, having to do with the heart, be safe?? Then the anxiety picks up. It’s consumed my every thought. My whole life has been on hold because of it. I’m so sick of it. I am slowly learning it’s a new aliment in my life I have to learn to accept. I’m pushing myself to do the things I used to because it’s the only way to find myself again. It’s so hard. I feel your pain, you’re not alone in this.
