I lost ability to talk at a young age due to traumatic experience. I wasn't totally unable to talk. I just got a real bad stammer. Yet to this day I still use text and email a lot. I can send things in email I could never articulate in real time conversation. I like idea of writing in diary and suggest you continue to communicate in anyway you can. It is a blessing to be able to connect with the outside world and caring souls any which way you can.
