I guess I feel protective of her, you know?
This is worth looking at. My 10 year old stepdaughter also feels very protective of her NPD mom. Mom calls drunk at midnight, SD coaches her through her tears, making sure she gets in the house safely. SD knows things she shouldn't know and constantly reassures her mom that she is the favorite parent. My husband can't see the harm done to his own daughter because he was raised that way and thinks it's normal. It genuinely breaks my heart to know that you, my SD, my husband, and so many others have gone through this.
But is it wrong to feel protective of a parent? If something feels off, it helps me to think about what could/should be. What's healthy parenting? Healthy parents take responsibility for their mental and physical health. They encourage independence and autonomy in their children, see a therapist or talk to a friend if they're lonely or navigating difficulty. An emotionally healthy mom who was diagnosed with cancer would go to regular check ups, follow Dr's recommendations, provide accurate updates for her concerned children, accept help from family and others with gratitude. She would not weaponize her diagnosis to guilt people into caring for her.
What kind of monster doesn't want to talk to a parent who has cancer?
You're not a monster. Just like others in this forum, you're an adult in the pursuit of emotional wellbeing. Your mom should be so proud of you for doing that. Unfortunately, she can't see beyond her own needs.
Re: your desire to protect and care for your mom, which is in conflict with your desire to remain NC: my BPD MIL desperately wants me to take care of her, move in with us, go shopping with me, have me drive her everywhere. It's excessive and draining. I battled through guilt and found creative ways to stay true to my tolerance levels AND love her in the ways I could - tiling her bathroom, painting, ordering an ancestry kit and doing genealogy research for her.
I needed to do those things for her because it's important to me to be a supportive, loving DIL and wife.
If you feel strongly that one should protect and love a parent, will it make you more conflicted, angry and sad to completely disregard that value? Is there a way to creatively honor that value AND respect your desire to remain NC? Set aside some money to help her with medical bills, deliver the funds through a family friend? Anonymously order a few meals to be delivered to her house when she's undergoing treatment? Anonymous gift card for a manicure or massage? Even a thoughtful, anonymous card? For your sake, maybe write a letter you wish you could send outlining your desire to care for her and the reasons you can't?
Man, I could go on forever with this if I let myself. This is what bothers me--she is so unaware (or perhaps she's aware and doesn't care) that she has the power to knock me into a spiral of guilt and trauma.
Regardless of the other person's motivation or awareness, I hear you on this. I'm no expert, but in my experience, it gets easier to refuse to jump on the spiral. My current mantra is, "They can put the blame on me but I don't have to carry it." The outcome of your mom's diagnosis is not yours to carry. What part of this is yours? Is there more processing and grieving to do? What are your values and how can you stay true to them? What options do you have?
