My Social Security Disability claim was approved largely because I had well documented major depression - both diagnosed and under treatment. After I lost my job related medical insurance and applied for another policy, the fact that I was undergoing treatment for depression counted more points against me than my Parkinson's, and I was denied. The insurance industry is well aware of the disabling nature of depression.
Boann, you are strong to have been able to defeat your depression and keep working despite your PD. I, so far, am not able to do so. The PD is one matter; the depression I should be able to conquer.
I do not play nice when it comes to a challenge of the "legitimacy" of depression as a real and dangerous disease. That is what I assumed from your posts; obviously I read you wrong, and I apologize for that.
Here is a music video I made 5 years ago about how I see the impact of "non-motor" symptoms. It has taken years to get the PD organizational establishment to pay attention to us, and to even begin to understand how the so called secondary symptoms of PD destroys lives.
Don't worry - it goes fast, and, hopefully, you'll appreciate the humor
