So sorry Sylvia to hear about Bluey's loss

I agree completely, animals have feelings and although we shouldn't think they are the same as ours, they definitely know when they are unhappy and you can always tell if you know them.
However I'd like to be the devil's advocate for your vet: s/he (but I think must have been a man if not very sympathetic

) probably just saw that nothing was medically wrong and said what was logical to say: leave it a bit and it will get better. There really are no medicines for that sort of loss, and I'm not convinced one should start giving anti-depressants to sheep!
Nobody could have predicted that Bluey would have died of heartache - some sheep (and people) do, some don't. It's natural diversity.
Still, so very very sad for your loss and hope it does not happen again xx
