Did anyone else cry after Lord of the Rings?

I just finished The Lord of the Rings books, and at the very end, when Elrond, Gandalf, a few others, and FRODO leaves, I cried so hard. I get why Frodo had to leave, and Gandalf and Elrond, but all the same, I felt incomplete. Like, I felt that the author didn't really finish, and there's more to it. And I can't stop feeling like this! I'm like, depressed. And seeing the end of the movies just made it worse! Anyone else feel like this? And if you did, how did you get over it?
