When you seriously admire people's writeups of what PTSD is, because you don't need to distribute your short version to people.
(It reads 'Incurable. Lifelong. Physically throws you to the worst moments of your life at complete random. You don't want this shit.')
When PTSD forums make you happy, because they declutter what was you, what was messed circumstances, what was messed works, what health problem fits where, and what's all the simply human, yo, stuff. Lightbulb.
And you feel normal.
When ... busy feeling, forgot words, but once in a while words didn't just sublime away. Huge improvement in your sense of interpersonal communication.
