If you have to type an email or a message that is about a sensitive topic, or one that you have trouble discussing, type it out in a notepad-like application instead of the email/message app instead.
Its much easier to be honest, forthright, and frank when you're just putting text into a blank document, without the pressure of seeing the person's name, avatar, online status, etc.
I need to do this when discussing family problems or addictions with people. Really helps.
@gentoorebel I though I was the only one who did this. I also delete the To: field while composing in order to avoid accidental sends.
