i feel like i'm constantly running on empty and can't focus. do you have any real advice for regaining my mental clarity before i completely collapse?

i completely understand that heavy fog that settles in when your to-do list becomes a mountain. last quarter, i was skipping meals and losing sleep just to keep up with my inbox, which only made my productivity plummet. To avoid burnout at work , I downloaded the Headway app and was able to take control of the situation , by identifying exactly where i was on the stress spectrum. once i saw the stages laid out, i started setting rigid boundaries. i stopped answering pings after six and focused on micro-learning to reset my brain. it really changed my perspective on success.

thanks a lot guys
