What worked for me was to face the next HOUR. Not the next week, next year, or 10 years into the future.
Plus, the energy you spend coming up with future scenarios is wasted time. Seriously, now is the time to START detaching - no one is expecting emotions to shut off, for you to not hurt, for you to not be stressed, or that there won't be moments where life just plain sucks.
Just take on the task of getting started - get through today, then start working on tomorrow.
