How do I practice mental diet when my job puts me in a constant state of panic?

From what I understand I still need to interact with the 3d and acknowledge the constraints I work with, but shouldn't let them impact my state of being, right?

I find it easy to enter this state in weekends and early in the morning, but when shit starts breaking at work and I have a bunch of emails putting a fuckton of tasks on my lap with noone ro delegate to, it stresses me the hell out and it's hard to get back to imagination
