I Wan't To Die!

So as I came home last Friday a cute little female pit-bull came up to me and sat down just before I opened the door to my house, it had a collar but no tags. I ended up keeping the dog up until tonight and for this entire time I have been trying to find a owner the dog keeps teething and chewing on everything, and now the dog has tor up a old pillow of the family's and I've been getting my ass chewed out over everything the dog does! I'm tired of it and want t give up, I don't even want to go to school tomorrow, I just want to die already! Either way tomorrow is the last day were keeping the dog so it will be gone. . .
