I find that I don't really pay attention when a room is too hot or too cold, for instance. Often, someone else has to say something before I even notice.
I find that I can neglect a lot of my own physical needs for a long time because that isn't what I'm focused on..I am very other-focused, whether it is in a friendly way or in a competitive way.
I worry a lot about what others think about me but can completely not be bothered by physical needs..for instance, it doesn't bother me if I'm feeling hungry or feeling tired..I barely notice it..I'll get food or sleep eventually.
On the other hand, I go all out with anxiety/frustration when someone I care about is mad at me for something or I suspect that there is something I did that they didn't like..that's something I can't stop focusing on..I have trouble concentrating/functioning on whatever else I have to do until that problem is resolved.
