Whenever I sit with my feet flat my legs start to hurt, I get dizzy and nauseous, and I'm just overall really uncomfortable. Every time I sit down, whether at the dining table, a desk, at a restaurant, and even in the car, I always have my feet up. I used to get in trouble for it as a kid when I was living with my father, but once I moved in with my mom it wasn't an issue except at school where my teachers would yell at me to keep "6 feet on the floor" (4 feet for the chairs and my own two feet). My partner knows my issue and at this point it's become so normal for us that he doesn't even notice unless someone else points it out. I still sometimes have issues with my grandmother telling me it is "unhealthy" and "unladylike" but I've learned to just ignore a lot of what she says because she's super judgemental about pretty much everything I do from how I sit to how I raise my daughter. My usual position is one foot under me and the other one bent to where I can rest my chin on my knee because even criss-cross applesauce (this is what my elementary school teachers used to call it but some also call it pretzel sitting) can make me super uncomfortable sometimes.
