The link to Narcissism: after surviving a narcissist’s Discard, most people find it impossible to get out of bed. It is extremely difficult to shower or bathe, to brush your teeth, to put on clean clothes, to take care of your physical needs in any way. This is the result of the slow, steady brainwashing that the narcissist used in order to completely destroy their used-up toy. You can read about this in a thousand blogs. When I was lying in bed for the months of November, December, January, and February; I knew that walking would make me feel better, but it was freezing outside and the sidewalks were treacherous with ice. For months, I only left the bed once a week to get groceries. It was dire.
Lack of physical activity and exercise does lead to illness, and narcissistic abuse does lead to shutting down. Therefore, people do get physically ill from the narcissist.
But, remember, it does get better. You will get better. Just do what you can for now. xoxo
