Well yeah. But thinking the way you did wasn't stupid, it just was the way we're taught to try and ignore or fix ourselves. You can't fix PTSD.

But you will get better if you continue, however slowly, to learn to accept yourself, to identify what is PTSD and not really "you" and not beat yourself up. It is a beast of a disorder.

Yes, the sooner someone who experiences a trauma receives help, the less affect the trauma has... it's something about countering the brain chemical dump... and it's why we have debriefing sessions after trauma work for the volunteers...(and always in the military after a mission etc, but now they know how extensive that debriefing needs to be to be truly effective.)

be as well as you can be, and let that be good enough for today
