It is a really hard thing to do, I know it, I've been there so many times. Listen to what the vet tells you as to if your cat is suffering, and act in his/ her best interest.
P.S. If he's barely breathing, he may be in shock and not aware of where he is. Just talk to him so he can hear your voice, pet him like you usually do so he knows you're there, and let the vet do what he has to do, IF nothing else can be done.
I am really sorry, OP.
