Hi all - I (24F) have terrible health and medical anxiety. I got my Covid 19 booster today and I am having constant panic attacks

I know I need to booster to protect myself and others, I believe in the science and hope everyone gets it! Logically I know it’s fine, but my brain is programmed to think anything entering my body that is a vaccine or pill is scary. Anyone have some reassurance?

I’m also constantly thinking my panic is a symptom/side effect of something from the shot :( holding I’m not alone in this
