so stop bullshitting yourself.
Take one task at a time and close the loop on it. Just kill that task (even if it as small as replying to your agency about an upcoming event) before you move on to the next one. You will amazed that you can actually get work done.
If you have an over-spilling priority list which is leaving a lot of displeasure across different teams as a residue, then there is a different learning hiding there.
Side Note: Priority list in its right sense is a welcome change agent.
