Thank you guys!
I really needed the support...
My friend is in South America, she called my cell today but I was in class and couldn't answer the call. When I got home I saw she had sent me an e-mail apologizing for not replying before (I had sent her 2 e-mails since Bob started refusing to eat), but she said whatever has happened she was sure I've done the best for him. By the time she sent me this e-mail she didn't know he'd died. I just sent her a reply telling her the bad news

Now it's Leonard, my little red cap, that is dying... I'm always trying my best, but sometimes I feel like I'm hitting walls...
