Anxiety with newborn

So my 2 week old has like a little bit of a runny nose and a small cough and she grunts a lot but other then that she seems good she eats a lot and sleeps good and has a good amount of wet and poppy diapers but I got on tik tok and saw stuff about rsv in newborns and smaller children and now I’m just scared that she has it because of the grunting and stuffy nose ik I’m probably overthinking but I just get anxiety and always think something is wrong with her it just sucks 😩
