Terrified

So, I'm feeling really scared right now. My pet, Claire, has been tossing and vomiting for hours and she hasn't stopped. I can't take her to a vet right now to know what the hell is really going on, and my mum said that I'd better be prepared because there's a probability that she's poisoned. I feel just terrible and my mum just went to sleep, just like that! She's like... oh so insensitive. Now i'm terrified that my dog dies, and I won't sleep tonight so I can check on her if she's alright and clean up her vomit :( I feel very sad, but I'm terrible scared that she would die and I won't be able to do anything... So right now I'm planning to miss school tomorrow, and just pray for Claire.
I really don't want her to die. I'm very concerned
