Health anxiety heart palpitations

Since the holidays I’ve been having these palpitations. I’m no stranger to them, and had a holter in 2022 and a few other ones throughout my life. They are just so frequent now. Like a few every minute at their worst and then taper off for a little and return. It’s basically all day. I don’t notice them as much when I’m busy and I have no other symptoms besides panic and frustration when I feel them. I went to my doc recently and he ran a CBC, vitamin b&d panel, and thyroid panel and it was all normal. My sleep obviously is crud from my other post. I also have health anxiety so I think about getting the palpitations throughout the day a lot. Probably once every few minutes honestly. It’s one of my first thoughts when I get up. Idk if anxiety can actually cause them though. Any other reason for these that I might be overlooking? They are so unsettling getting them like a few times a min. I can deal with a few times an hour.
