i can totally relate to this. i also have an eating disorder going back to childhood that exacerbates/ is exacerbated by my CPTSD dissociation. eating enough has always been a problem for me.Due to dissociation, I forget to eat for large chunks of the day. My blood sugar crashes, leading to all sorts of associated symptoms including anxiety, overwhelm, confusion.
Due to the dissociation, I don't notice/ understand that I've forgotten to eat and that my blood sugar has crashed, which is why I'm feeling so bad.
So I continue not to eat, feeling awful and stuck in dissociation.
This pattern has been going on since childhood and started in childhood because of neglect and only having access to food at sporadic times during the day and going long stretches without food.
I've always been used to going without food - it doesn't even really bother me.
