usually to people from your past, or maybe not. any text that you know better than to send right now, or ever. texts of things you wish you could say, or that you're thinking, but can't share for whatever reason.
this may not be a healthy way of going about it, it might be a form of holding on when i need to let go. probably no better than talking to myself. but i find that:
1. it gives me that feeling of release, that i got it out of my body and it isn't burning on the inside of my skull anymore, which is usually what drives me to send texts like this in the first place
2. it brings a feeling of strength and pride when i DON'T hit send. when i backspace the whole thing. i typed it out, and it was 1 send button away, and i still didn't bite. that must count for something
