When I'm feeling paralysis around completing an important task, I use a kitchen timer to help me move forward. I use it for all sorts of tasks. Whether it's a dresser drawer a closet that needs to be cleaned or a desk that needs to be organized, the timer can truly be your friend. It works for anything!
By using a timer as a tool, you're getting the task done with the added benefit of emptying your head from constantly "thinking about getting the task done". Over thinking a task creates stress, and IT’S an energetic drain! You can stay with job for the ten minutes or you can decide to increase the time and finish another round. You're in control. Be conservative about your time increase in the beginning. Whatever you do start with ten minutes and work until you hear the "ding".
