You are just finally coming around to understanding the true scope of the amount of work you have to do today -- at your job, in a romantic partnership or in a friendship. This sudden realization could overwhelm you, but it doesn't have to. The soldier in you knows that you can do this! No task is too tough for you, especially if you are humble and honest about how you're feeling. Reach out to the other person (or people) involved in this task, and get them to contribute to the solution.
