Option B, shamefully fearful, does not directly relate to the emotional state associated with being an invalid. Option C, injured, does not capture the emotional aspect but rather focuses on the physical condition. Option D, symbiotic, refers to a mutually beneficial relationship between two different organisms and is not relevant to the emotional state of an individual after becoming an invalid.
