It's quite understandable that you're grumpy. You are allowed to be grumpy, even without a reason but especially with sad news like this and with the feeling of helplessness when you think you can't do anything. Except be there for Faith and that's actually doing a lot.
It's the feeling of helplessness that makes it the worst I think; It's like I'm a passenger. We'll rock on though, there's no other choice really, and I'll have a rant here now and then if I have to. Thanks for your message. :)
