"The worst way to miss someone is to be sitting right beside them knowing you can't have them." This or something resembling it is a very well known quote. It's on blogs everywhere, and I believe in books of quotes. I'm afraid that I don't know where it originates from, but it may be possible to do furhter research on google?
