Been given antibiotics for a chest infection today, I hate taking tablets as I am scared of side effects to the point that when I have taken something I automatically feel panicky and anxious

Had an amoxicillin an hour ago and feel well out of it here at work and jittery and anxious. I'm sure it's just my mind but it's scaring me

Doc said my temp was normal and oxygen ok but it's making my breathing feel odd

Anyway just getting it out there
