It is okay to let your emotions go on "paper". I used to type up my e-mails and text messages, but before hitting the send button I paused got up and went for a walk.
When I returned, I read through what I had written and amazingly realized how full of anxiety and weakness those messages were. I found myself very unattractive.
Most of them were never sent.
It's a great feeling when you have control over yourself.
