Where is it possible to get a hold of dissociative disorder?

It's not possible to "get a hold of" a dissociative disorder. Dissociative disorders are mental illnesses that can develop due to a combination of genetic and environmental factors, such as trauma or abuse, and are not something that can be acquired intentionally. If you or someone you know is struggling with symptoms that may be related to a dissociative disorder, it's important to seek help from a mental health professional for proper diagnosis and treatment.
