It's healthy to keep a diary. That way, you'll be able to get all of your feelings out on paper--or on a screen. Since it'll be all too easy for your parents or roommates to find your diary hidden under your bed, you should think about using the Internet to talk about your day. That way, no one will ever find what you've written. Here are a few websites you can use to keep a diary:
1. Live Journal
When you make an account on Live Journal, you can make posts for other people to see, or you can set them to private, so you're the only person who can see them. Every time you post a new entry, you can type in a title, your current mood, the music you're listening to, and your location. You can even add GIFs to the posts!
