I, too, am feeling sad and have a sense of loss.  I had just finished reading all of the books just before AMoL was released and jumped right into it.  I finished the book last night and couldn't sleep because I kept thinking about all that happened during the LB.  Reading the final chapter and not wanting it to end.  I wanted to read more and find out what happens to the remaining characters in the 4th Age.  I find myself almost in tears when I start thinking about it.  I have read some many books and not a one has ever made me feel like this one did.  Call it good, call it bad, but it was an ending.  In a story where there were no beginnings or endings, this was a end.  It was an end to the greatest series ever written.  Thank you Robert Jordan for giving me such a wonderful story.  I laughed, I cried, I read and now it is over.  Sure there is the ability to reread the books, but it won't be the same.  I won't feel the anticipation of waiting for the last book.  I almost wish I wasn't so impatient to get the final book.
