Sorry to hear you had that experience.
I'm sure your mother's neglect didn't help, even if it wasn't the root cause.
I'm the same way taking water to bed.
I'll panic if I don't have a lot of it within reach.
When I was growing up, we didn't have breakfast except Sundays.
Sundays were for bacon and eggs, which made me sick.
The other days of the week no one had "breakfast" before work or school.
I don't remember my family ever having lunch, ever.
On school days I walked home at lunch for a sandwich, because they made me.
Kids weren't allowed to stay at school during lunch.
My parents, brother and I never had "lunch" together even on weekends.
My mother made supper but I took it to my room and ate alone.
There was no emphasis on whether I had a balanced meal beyond what she cooked.
It didn't matter if I ate it all or not.
We didn't have snack food around the house either.
All I remember as a snack were Fig Newtons.
There was never any fresh fruit in the house except occasionally some berries.
I wonder if this messed me up too?
I'm sure that did mess you up, it set your body into an unhealthy mode of not knowing when you're hungry/thirsty. I think experiences like ours confuse our bodies because food and drink is connected to emotional states.
My mother is very, very immature emotionally, I've realised. She doesn't understand emotions or problems or giving support to other people. She talks the talk and everyone thinks she's wonderful, but when it comes to ACTUALLY supporting people, she is dust on the horizon. Especially her own daughter, me. She's always had a grudge against me, I don't know why, and enjoyed treating me badly.
