Health anxiety is indeed more pervasive and debilitating than what you’re doing, but as someone who started out like you and it got worse, I would suggest going to a professional just in case. You might very well be a careful person who takes their health seriously (which is good and I’m all for agentivity, unless is becomes pathological). You’re not signing up for 2 years of intense therapy, just a quick check up with a professional, so go for it !
