If I Could Go Back and Talk to Teen Me

When my little sister was diagnosed with leukemia, I was in high school.

She was five years old.

I remember crying at first, the kind of crying where your throat hurts and you don’t know what to do with your hands. And then I remember being angry. Not “a little upset” angry. Real anger. The kind that sits in your chest and makes everything feel unfair.

People tried to comfort me. They wanted to hug me. They wanted to say the right thing.

And I didn’t want any of it.

Not because they were doing something wrong. I just didn’t know what to do with the fear. I didn’t know what to say. I didn’t know how to be a teenager and be terrified at the same time.

I remember thinking things I didn’t know how to say out loud.

Like... why her?

Why would something like this happen to a little girl with the brightest blonde hair and blue eyes... The kind of kid who felt like sunshine in a room?

And while all of this was happening, we had another little sister too, she was only one... maybe two at the time.

She had no idea what was going on.

All she knew was that her sister was “gone,” and everything at home suddenly looked different.

Our dad was ripping the house apart. New rugs, paint, you name it, trying to make everything clean and safe so our sister could come home. Looking back, I can see what it really was: love. Preparation. A father doing the only thing HE could control.

But through a toddler’s eyes, it looked like destruction...

In her world, the house was being “ruined,” her sister wasn’t around, and the adults were emotional and distracted. Dad and his friends were tearing things up, moving furniture, painting, hauling things out.

And for a little while, it was mostly just me and her.

So I had to be the big sister.

I had to make her smile. Keep her busy. Keep things light, even when my mind kept drifting back to my other sister fighting for her life.

I don’t think I realized it at the time, but I was carrying two worlds at once: a toddler who needed joy and safety, and a reality that felt terrifying and out of my control.

It was confusing for her in a way she couldn’t explain. And we had to be strong for her too, because she needed stability, even when we didn’t feel stable at all...

That’s the part people don’t always realize about crisis and grief in a family: it’s not one person’s experience.

It’s everyone’s. And it’s layered.

It’s grief and fear, but it’s also school and siblings and dinner and trying to keep things normal when nothing feels normal.

If you are a teen going through something like this, a serious illness, loss, or the kind of fear that changes the way you see the world, here is what I wish someone told me back then:

You are allowed to be angry.

You are allowed to not know what to say.

You are allowed to not want to be touched.

You are allowed to be “fine” in public and falling apart in private.

Grief and fear don’t always look like tears.

Sometimes they look like shutting down.

Sometimes they look like snapping at people you love.

Sometimes they look like wanting to be alone.

Sometimes they look like laughing at something and then feeling guilty for it.

And sometimes... especially as a teen, they look like trying to be strong because you think everyone else needs you to be.

I felt that.

I felt like I had to hold it together. For the adults around me. For my little sister who was sick. For my toddler sister who didn’t understand why her world was upside down.

But the truth is... I was still a kid too.

If you’re a teen reading this and you don’t know how to talk about what’s happening, you’re not failing. If your feelings feel “too big,” you’re not broken. You’re responding to something that is too big.

And if you’re someone supporting a teen, this is one thing I’ve learned:

Sometimes the most helpful words aren’t advice. They’re permission.

Permission to feel what they feel.

Permission to be quiet.

Permission to be messy.

Permission to not have the “right” reaction.

Here is something else I wish I knew:

Time doesn’t erase what it was like, but it can bring breathing room.

On January 12th, 2026, we marked my sister’s 20th year in remission.

Twenty years...

That number still feels unreal to me sometimes.

We can breathe.

And when I think back to teen me... Angry, overwhelmed, unsure how to receive comfort, I wish I could tell her this:

You’re not wrong for how you’re feeling.

You’re not weak for how you’re reacting.

You’re human.

If you feel comfortable sharing: did you go through serious illness, grief, or a major loss as a teen? What helped you feel even a little more steady and what didn’t?

You’re welcome to share in the comments. And if reading quietly feels safer today, that’s welcome too.
