On the contrary, I think paralyzed is quite an accurate depiction of the effect of severe depression. Most people still don't consider mental conditions on par with physical conditions, but that's simply not true, those severe mental conditions' are the result of neurological damage in the brain. In that sense, the person is paralyzed just as you are as problems with his neurological system limited his movement. Spinal cord is also an important part of our neurological system, it's essentially the southbridge of our body, but wouldn't it be funny if we call southbridge damage resulted inability paralyzed, but CPU damage resulted inability not? I get your point where you think spinal cord injury is more physical, but those mental conditions can be just as physical.
