Things Happen For A Reason

I’m having a little trouble believing that right now. My dog is at the vet and she might have to stay overnight. She’s only little and she hasn’t been eating, she’s had diarrhea, and she’s just not herself. She might have a blood problem, and they are doing all these tests. My dad has to pay $700 for it, and we don’t have the money, so he split it into two payments. We can barely afford it, and my little dog might have some serious problems. So if everything happens for a reason, what’s the reason for this?
