I'm so sorry this is happening It's really hard to see our pets struggling and not really know what's going on. Does he seem to be in any pain? It might be worth calling your vet just to see what she says. Even if she wants you to bring him in you don't have to, you could just say that you'll wait a few hours and see how he is then. I know if it was me I'd be tempted to keep him at home if he didn't seem to be in any pain. But then I know with animals it's hard to tell whether they're in pain or not. I'm sorry this is bringing back bad memories for you. I agree calling t to ask him to call his brother isn't really what he's there for but maybe you could call him and get some support.
