I suffer from executive dysfunction (or nonfunction) but:

Kurra, you did it tonight. You signed one paper you needed to, without too much delay. Now go draw like a sunuvafish and enjoy and sleep better. Also, you checked and you were never going to make the payroll dedline because your latest job ran right through it. There was nothing you could be expected to do, so update your other work paper, do your payroll tomorrow, and take on more contracts tomorrow. You may not forgive yourself but you can have amnesty.

As long as you are willing to work existing obligations and promise to minimize new obligations and keep those in a timely fashion, you should be allowed to feel and enjoy the privileges of being human. Sleep well, wake early tomorrow, exercise, and complete your amnesty requirements.
