Someone I know with a narcissistic personality has been recently diagnosed with cancer.They are having angry outbursts, being punitive to friends and family who offer support, then blaming others for not caring enough, blaming the doctors.It seems everyone else is at fault and they are the only one that's right.
I am a cancer patient myself and I am very exhausted by it.

Members offered thoughtful advice on how to support someone with a narcissistic personality after a cancer diagnosis without sacrificing your own well-being, especially as a fellow cancer patient. Several members emphasized that protecting your peace and energy is the top priority, suggesting clear and firm boundaries, limiting interaction time, using practical workarounds like disposable meal containers, and being prepared to walk away if boundaries are crossed. A recurring theme was that you cannot be rational with irrational people, and that seeking counseling or a cancer social worker may help the person in need if framed around the cancer itself.

Having lived with narcissistic people, I have one suggestion: run! Unless you have no choice. I think self care is the first priority when going through cancer treatment. Your body needs all of its resources to take care of you right now. I think setting boundaries is a great idea but the energy to hold to those boundaries as they are challenged repeatedly can be better used for your own recovery. Be prepared to be guilt tripped if you choose to distance yourself. Please remember, it’s not selfish to put yourself first, especially now. Wishing you the best, whatever you choose!

Take care of yourself first. You probably have limited energy at this point. I've pulled back from a few relationships that cost me too much energy!

My ex had that trait combined with being bipolar. My former sister in law has borderline personality disorder (BPD) which is a lot like narcissism on steroids. From your description your friend is behaving right now like someone that may have BPD.

The word "run" is great advice, but I know you're a good person and want to assist without getting your head ripped off. Some of the things I learned are you have to be prepared to say no and to stick by your no. You need to be prepared to turn your back and walk away, either temporarily or long term if need be, if this person crosses certain boundaries that you set.

It can be a hard discussion, but tell this person you are trying to help and they could benefit from your help because you're walking down the same path in life. Tell them you are setting certain boundaries for your own well being and if those boundaries are violated you will be walking away. Tell this person the boundaries. This discussion will most likely set them off and you will most likely need to walk away.

If they have a husband, boyfriend, or family member who is this persons main support and punching bag you may want to explain to them what you are doing and why. If you want you can let that person know you are there for them if they need to talk, but you need to take care of yourself and abuse from their cancer patient is not something you will tolerate. It's really common for those who are closest to the problem person to enable their behavior and make excuses for them. That is their own fault and problem if they want to be treated like a doormat, not yours.

There were multiple times my ex banned his sister from our home for a year or more at a time. Once the exile period was ended she would behave for the next 2-3 visits and then revert to her normal BPD self and get banned again. It's a lot like dealing with a 2 year old that is going through the "me,me,me" phase except they never outgrew it.

Many people will try to do and say whatever they can to placate the problem person in an attempt to avoid the unpleasant outbursts, but that never really works and it condones the bad behavior. Over time this person should adjust and accept what they can't change and their behavior might scale back to their normal level of narcissism or they could get worse. It's a crap shoot.

They should definitely be advised to get a cancer social worker and get some kind of cancer related counseling at a bare minimum. They are more likely to do it if they believe it's for the cancer and can blame it on the cancer as opposed to getting help cuz they are the real problem.

That being said, you need to do what is right for yourself and your well being. Taking care of yourself is what is most important and setting boundaries with this person, even if it ends up being the end of the frienship, is what is most important to do for you and your well being. Good luck β€οΈπŸ€žπŸ™

@A MyBCTeam Member, I agree with everyone who says to put yourself first. I am truly sorry that this person has been diagnosed with cancer and I hope the outcome is a good one, but you need all the strength and fortitude you've got to get yourself through this. As much as we would like to, we cannot save everyone. You must be strong for yourself. Don't take any guilt trips, and prepare to remove this person from your circle.

First, it's worth acknowledging that managing your own breast cancer while supporting someone else going through a diagnosis is genuinely exhausting. Your wellbeing has to come first β€” you cannot pour from an empty cup.

It's actually very common for people newly diagnosed with cancer to express anger, frustration, and even lash out at those closest to them. A MyBCTeam member once shared feeling "angry, sad, frustrated" and struggling mentally even while managing treatment. These emotions are real and valid, but that doesn't mean others are obligated to absorb them without limit.

Here are some ways to support this person while protecting your own peace:

- Set clear boundaries β€” decide in advance how much emotional energy you can give, and stick to it
- Be specific with help β€” offer concrete, limited support like dropping off a meal rather than open-ended emotional availability
- Step back without guilt β€” it's okay to take space when interactions feel harmful to you
- Encourage professional support β€” gently suggest they speak with a counselor or social worker who specializes in cancer-related emotional support
- Protect your own mental health β€” lean on your own support network and consider speaking with your care team about caregiver fatigue

You are not responsible for managing another person's emotional response to their diagnosis, especially while navigating your own.
