If you desperately need to get something off your chest, and you just really need to tell someone but don't know who or how, then download the Whisper app.
Whisper is a mobile application where users can anonymously tell each other secrets, read one another's thoughts and communicate their deepest undisclosed information. These messages are imposed atop an image, and can range from comedic matters, to more serious thought-provoking contemplation. All of the entries end up on the Whisper homepage and are accessible to anyone visiting the site.
If you're dying to tell someone something, but have a hard time trusting the people you know, you ought to download the Whisper app. The act of releasing your deepest thoughts will relieve so much tension and stress off of you, you'll be relieved that you told someone.
