Camp Woes

Carter arrived at camp yesterday, having been driven there by his friend's dad and at around 3pm the sobbing phone calls began. Last night after dinner he threw up (though he may have been dehydrated). I have talked him down a little, but this morning he called me again, still sobbing, begging me to pick him up. He hates it. They are getting ready to go snowboarding now, but my sense is he is too distraught to actually participate and find it fun.Do I ruin my first week alone with Olivia to go and pick him up (a 4+ hour drive)?
