You're driving home. Out of nowhere, you picture your child's first day of college: you making up their dorm room bed and wishing them luck with a hug. Or maybe it’s the image of stepping into a hospital room; not for treatment, but to hold your first grandchild in your arms.

Maybe it’s as simple as next year's birthday party with a bounce house and your kid’s favorite cake.

Then the guilt hits, fast and sharp because you’re not considering the future with anticipation. It feels a lot more like a deep, unshakeable grief.

Medical diagnoses, cancer or otherwise, change what your child’s life looks like. The things you hoped for them suddenly feel like they might never happen. Maybe you feel guilty, because it makes you feel ungrateful for the child still in front of you.

You can love your child completely and still grieve the future you'd already started picturing before diagnosis. One doesn't cancel out the other.

This isn't about loving your child less.

Grief happens whenever an expectation gets rewritten, even when the person you love is still very much here.

Before diagnosis, you probably weren't consciously picturing every milestone, but you were carrying an assumption that the road ahead would be ordinary and uninterrupted. That it would come with all the “normal” milestones every kid should have.

Cancer changed that assumption, and the mind grieves changed assumptions the same way it grieves other losses.

That grief isn't a betrayal of your child, and it isn't a sign you love them any less than the parent who feels only gratitude.

The Scorekeeping Trap

Many parents feel like they're only allowed one emotion at a time. Cancer dumps several on you at the same time, for months, even years. You can be moved to tears by how your child is handling a hard week, and also mourn the life where this never happened, sometimes within the same hour.

Parents can wind up doing internal scorekeeping: if you're sad about the future, does that mean you're not grateful enough for the present? If you're picturing worst-case scenarios, does that mean you don't have faith that your child will get through this?

None of that is how it actually works. Feeling one thing doesn't cancel out the other, and it isn't a measure of how much you love your child. When it happens, try naming it plainly instead of arguing with it: "I'm having a hard moment, not a disloyal one."

When Grief Becomes Catastrophizing

There's a difference between grieving a changed future and spiraling into worries of the worst future. It's easy for one to slide into the other, especially late at night or after a hard appointment, when the mind jumps from "this is scary" to imagining every possible bad outcome, including ones far beyond what your child's actual situation suggests.

What is catastrophizing?

In psychology, catastrophizing occurs when a person anticipates the worst possible outcome, regardless of objective evidence to the contrary. It is an exaggerated and misguided defense mechanism rooted in discomfort with the unknown. In a way, it is the brain “preparing” for disaster to protect you from future disappointment. Cancer parents may be prone to this, as the cancer diagnosis itself is often considered “the worst that could happen.”

If you notice that spiral starting, bring yourself back to what's actually true today: this scan, this treatment, this week. You can grieve without falling into despair.

If the spiral keeps returning, it's worth mentioning to your child’s care team or a counselor who works with families in treatment; they can help you separate real risk from feared risk, which is a hard distinction to draw on your own.

Connecting with another cancer family further along in treatment can help too, since they can relate better than anyone and—in some cases—are on the other side of the trials you’re currently facing.

Love and Grief, Colliding

You don't have to choose between grieving what changed and loving who's in front of you.

Give yourself permission to feel the loss of the future you'd imagined. Grief (even this grief) is proof of loving deeply. There’s nothing wrong with hoping for the very best for your child and being disappointed when they’re faced with something this difficult and life-altering.

You loved the future you imagined for them, and you love this child, exactly as they are, right now.
