Thanks for the replies, I took the dog for a walk, then made some rice when I got in, helped the racing head a bit. I am really concerned for my mum though, my behaviour is having a terrible affect on her. I sent a text to let her know the dog was ok and to thank her for looking after her for a couple of days, and asked her to text just so I know she's ok and then I wouldn't bother her, and i've had no reply. I can't stop worrying I might have made her really ill or much worse this time
