Still sick

I absolutely hate having a sick kid.  Thomas was fine most of the day yesterday.  He even ate pepperoni pizza for dinner!  This morning, he followed the same pattern as yesterday morning...was up for a short period of time and vomited.  Of course this is so odd, and my anxiety and neuroses automatically go to very bad places in terms of what could be wrong!  Hoping and praying this odd patterns comes to and end and all is well!
