10+ Mental Illnesses Caused By Staying With A Narcissists

1. Stress Creates Free Radicals That Kill Brain Cells

We are familiar with the phrase stress kills. But you probably didn’t know that stress slowly kills your brain cells.

Living with a narc who gaslights can be one thing but then trying to explain their insanity and nefarious actions to someone can be HELL.

And this is due to how much they damage their victim’s minds.

Check out this article “How Free Radicals Destroy the Brain & How Glutathione Can Help“.

2. Stress From A Narcissists Can Cause Your Hippocampus Shrinks

If you ever find yourself doubting yourself and questioning if you really “said that” or “did that” this is because the stress is shrinking your hippocampus, which makes it difficult for you to remember what really happened.

Narcs know exactly what they are doing and staying with them for the long-term (trying to make your love CHANGE THEM) will only do more harm to your mental well-being than good.

3. Stress From A Narcissists Can Cause Your Amygdala Inflates

For those who wonder why they find it so difficult trying to LEAVE THE NARC AND GO NO CONTACT, this is because stress with them makes it so that you feel a strong connection with them emotionally.

Having an inflated amygdala causes you to feel passion, hate, and fear at a higher level.

For some that passion (love) of the false person, the narc was while love-bombing makes that connection strong.

The hatred you have for them makes it very difficult for some to move on because we seek revenge.

And the fear of moving on can be crippling for many of us.

4. Stress Creates a Vicious Cycle of Fear and Anxiety

Walking on eggshells is not uncommon for those of us who have or are still currently in a relationship with a narcissist.

5. Stress Halts the Production of New Brain Cells

Excerpt from Power Of Positivity,

It has long been established that stress-related illnesses, such as post-traumatic stress disorder (PTSD) trigger changes in brain structure, including differences in the volume of gray matter versus white matter, as well as the and size and connectivity of the amygdala,” says endurance athlete, coach, and author, Christopher Bergland.

6. Stress Depletes Critical Neurotransmitters

Living with a narc can cause people to develop CPTSD and PTSD. It has long been known that children who grow up with narcissistic parents have the same brain scans of soldiers who have been to war.

Stress can lead to a myriad of other mental illnesses, such as:

  • Severe headaches
  • Chronic Pain
  • Insomnia
  • Anxiety
  • Depression
  • Change in Libido

8. Stress Makes You Stupid

Stress can lower your intelligence.

Excerpt from Prevention,

“High stress levels are not only associated with poorer brain functioning but may even link to an increased risk of Alzheimer’s disease,” says Brendan Kelley, MD, neurologist at The Ohio State University Wexner Medical Center in Columbus, Ohio

9. Stress Shrinks Your Brain

Excerpt from Yale News,

Experiencing stressful life events, such as a divorce or job loss, can reduce gray matter in critical regions of the brain that regulate emotion and important physiological functions — even in healthy individuals, Yale researchers report in a study published online the week of Jan. 9 in the journal Biological Psychiatry.

10. Stress Contributes to Brain Inflammation and Depression

Stress is a key factor in leading many people to depression.

  1. I was with mine for 12 years. During that time I went from slim to over weight. From looking younger than my years to looking older than my years. I looked pasty and ill. I look back at photos from that time and shudder.

    Within weeks of leaving her, people began commenting on how well I was looking. This was despite me sleeping on a mattress on the floor in a cold junk room at my brothers house. And obviously going through a break up.

    It’s damn true that narcissist are bad for you health. I truly believe she’d have been the death of me eventually.

    1. My heart goes out to. And I am SOOOOO HAPPY that you left.

      I wrote an article titled “Narcs are parasites and e are the host”.

      The more stories I hear about these people, the more I believe they are the living embodiment of sheer chaos.

      I am happy that you have left and are doing better.

      Feel free to join my Facebook PRIVATE GROUP!

      1. Thanks! Yes I’ve joined the Facebook group. The heartening thing is that narcissists are pretty formulaic. I think so much heartache could be avoided if more people learnt their patterns. I’ll take a look at that article!

    2. I was with mine for four years and looked like I aged ten years during that time. My body started hurting and I got intense depression and anxiety(never experienced this before). It’s only been about 2.5 months since I left, but already looking more vibrant and my eyes aren’t dead anymore. I took a picture of my broken self the day he devalued me and tossed me aside in October and comparing it to now is amazing….

  2. I have been with a narc for 5 years and never knew this. Finally I found myself at peace. But how to revive the brain from all the stress that accumulated over years!

  3. I was with a possible narcissist online. From February 2020 i have not had a full night’s sleep. Average 2 hours per night. He professed s undying love for me and then in the next sentence would demand money. He would call me all sorts of horrible names, saying i was evil and it was my fault that my family was in such a mess. I have just left him. I am a mess. I need help but i have no one to talk to

  4. Isn’t seeking revenge on a narcissist kind of narcissistic? I want my narcissistic family to pay, but if I mess with them the way they messed me up… then all the lies they told about me become true… I have C-PTSD, and multiple personalities, because of all this bullsh*t. I just don’t see anyway out other than suicide… I’ll never get an oppology, or remorse, or anything other than more blame… so why would I want to keep living in all this sh*t… It is better to exit than to keep living with abusers, or WORSE becoming somthing as discusting as a narcissist like my parents.
