Answer 1 question:
Can I do anything about this YES or NO ?
If YES - What?
if NO - LET IT GO!
If it's outside your control - Despite your desire to control it - let it go!
It takes work - but you can 99% of the time come back to the basic question at any point.
Even mid project you may still need to ask  "can I do anything about what/where it's at right NOW?:
If it's YES - What can I change about MY reaction / action / inaction
NO - Let it go. Take a breath and trust.
