When you are suffering with bad anxiety It feels like you tend to zoom on other peoples anxious thoughts (online and in general), like an anxiety bias; it's like you can sense their anxiety from their messages, and are more likely to accept their ideas and beliefs because of this.

I can see why sensing other peoples anxiety would have an evolutionary benefit - it could implicitly alert you of danger, before any direct warning was even said. Though, it's quite different in text-form, than just reading facial cues - weird.
