Do you believe that Depression is used by some as a form of manipulation?

I know a person who for all intents and purposes; who at least from my perspective, seems to be depressed on queue. When he wants some response from exhibiting the symtoms that just go away when he doesn’t actually want anything.

Do you know anyone who claims to have a mental illness, a disorder, or a habit like cutting or self harm who uses it to manipulate you?

Here is your place to vent!
