How Do I Get "Unfrozen" and Get A Move On?

You'll begin to feel better about the future when things are jumbled up in your mind, racing around wondering "where do I even start?!". 

That should read AREN'T jumbled up...

When I feel overwhelmed, I make a list.  Start with a small list...take 2 or 3 of your smaller, less pressing tasks and begin there.  Literally mark it off the list when you're done...draw a single line through it so that you can still see the task but it's obvious you've completed it.  When you finish those tasks, add more and continue the process.

Even though you might not be invested in it emotionally at first, as you accomplish a few things, it will serve as a "cheerleader" of what you've done and what you can do.  You'll begin to feel better about the future when things are jumbled up in your mind, racing around wondering "where do I even start?!".   You'll be moving on a few tasks at a time and you might even surprise yourself with how quickly you'll accomplish some of this stuff once you get rolling.
