I am only on my 3rd week of my traineeship and I already feel like this isn't the job for me

I didn't realise and nobody told me how sick you get working in childcare and my immune system is already super bad due to gladnular fever. Am I speaking too soon? Because I feel like I have already made up my mind about terminating the traineeship as I do not cope well with illness or get "manflu" as some might call it

I guess I had a different idea in mind for childcare but got slapped with the reality of it.
Any and all advice would be hugely appreciated!
TIA!
