A lot of people will know that anxiety and depression are associated with Parkinson's and that stress makes it worse. But not many people understand how much stress affects us. For me, stress is the real killer. I feel stress mentally and physically in ways which it could never even have understood before I had experienced the disease.
Remember, the very biggest amplifier of Parkinson's is stress. It locks PwP (People with Parkinsons') up into tight balls of pain and anxiety. Bodies become pulled into that classic C-shaped stance of Parkinson's, movement stops, muscles become knots of tensions, minds both close down and begin to race with negative thoughts at the same time. The mind and body rapidly amplify this negativity in each other. They trap each other and lock the other into unyielding positions of anguish and pain. For People with Parkinson's this escalation can happen very quickly - it would seem to me that we have become extremely over-sensitized to stress triggers. Little things can quickly be ramped up into crisis points.
So keep calm in voice and action as best you can and be always mindful that stress for a Person with Parkinson's is much, much more disabling and diminishing than for other people. I would also suggest to try to gently take away from a PwP any unnecessary responsibilities or unnecessary sources of worry too. I say gently, because having to admit that one can no longer cope like before, or that one is no longer as resilient, can be an extremely stressful thing to face and come to terms with in of itself.
