Just today it happened again. Sometimes, when I get anxious it spirals out of control and I start thinking about the worst possible scenarios, thinking I won't get through it or survive, seeing everything that can go wrong. The dread is so bad that I want to drop everything I'm doing and just lay down. But then, after a while, I come out of that fog like "well, if it happens, I got this", looking around, feeling like I just opened my eyes for the first time and things are suddenly brighter. It's not because I have some good coping mechanisms or I know how to positively talk to myself, that's why I wonder what it is. A few minutes ago I needed to sleep and for someone to hold me like a baby and suddenly I'm like "we'll see", looking around like the world is suddenly changed. 

Is that anything that has a reason, name, or have you experienced this?
