I may have overstated my point a bit, because everyone has a different base level of anxiety and tolerance for disorder, and everyone will also go through unavoidable periods of stress. I recommend (re-)reading The 7 Habits of Highly Effective People, Getting Things Done, and Deep Work if you haven't already.

I'm afraid my advice is not very original, but beyond a few common principles, getting organized is a very individual kind of thing.

I've read that most procrastination problems come from anxiety or perfectionism (fear of not being able to do X perfectly, low self-esteem / fear of being ridiculed for your work etc)
