Therapists say people who over-pack aren’t scared of forgetting something, they’re scared of uncertainty

I was watching my sister pack for a three-day trip.

She laid out seven outfits on the bed.

Then she added a raincoat, two pairs of shoes she didn't plan to wear, and a small bag of medications that looked like she was opening a pharmacy.

I asked her why.

She looked at me like I'd asked why she bothered breathing.

"Because what if I need them?"

I didn't understand it then. I traveled light. One bag, no backups, no "just in case." I thought her suitcase was evidence of anxiety she should probably work on. But years later, standing in a hotel room in a city I'd never visited before, I found myself wishing I'd packed an extra sweater. And a second phone charger. And maybe something nicer to wear to dinner.

I finally understood what she knew all along:

The extra weight wasn't the problem. The uncertainty was.

And for some people, having the stuff is the only thing that makes unfamiliar places feel survivable. Here's what's actually going on.

1. They bring two of everything

One charger is a gamble. Two is insurance.

Three means they've accepted that the universe is actively working against them.

It's not about expecting disaster. It's about knowing that "just in case" always arrives when they're least prepared for it. The phone dies on the train. The charger breaks in the outlet. The backup charger that worked yesterday suddenly doesn't.

According to Psychology Today , people who overprepare often do so because they've learned that relying on external systems—hotel amenities, local stores, even travel companions—feels riskier than relying on themselves. The extra cord isn't clutter. It's a promise they won't get stranded.

2. They pack for events that probably won't happen

A formal dinner. An impromptu hike. A funeral.

None of these are on the itinerary. The invitation almost certainly won't come.

But if it does, they refuse to be the person standing in sneakers and a wrinkled shirt saying, "I had nothing to wear." The embarrassment of being underdressed feels worse than the effort of carrying a dress that never leaves the hanger.

People often prepare for low-probability events not because they expect them, but because the cost of being unprepared feels catastrophic.  For the overpacker, showing up wrong isn't an inconvenience. It's a small humiliation they can prevent with one extra bag.

3. They bring the whole pharmacy with them

Headache. Bee sting. Heartburn. A sudden allergic reaction to a lotion they've used a hundred times.

All at once, all their own fault for not packing the antacids.

They carry bandages they'll never use. Pain relievers that expire before the bottle opens. Antihistamines for a pollen season that doesn't exist where they're going. Waiting for a CVS to open feels like a personal failure. Asking the front desk for ibuprofen feels like admitting they don't have their life together.

This is my sister to a T. She always packs enough medication to treat a small village.

4. They'd rather carry extra than ask for help

A safety pin. A phone charger. A bandage.

Asking a concierge, a friend, or a stranger for any of these things feels like defeat.

They'd rather carry a brick in their suitcase than admit they forgot something. The request itself—"Do you have an extra?"—lands in their chest as shame. They should have known. They should have prepared. The fact that they didn't means they failed.

This isn't about pride, exactly. According to Stanford University, for some people, asking for help feels the same as being wrong . The overpacker isn't being stubborn. They're protecting themselves from a feeling that has never once gone well.

5. Adding one more thing quiets a small fear

There's a specific relief that comes with zipping a full suitcase.

It's not about the stuff. It's about what the stuff represents.

Every item they toss in quiets a small "what if." What if it rains? Pack the umbrella. What if the restaurant is fancy? Pack the nice shoes. What if I spill coffee on the only clean shirt? Pack a backup. Each addition subtracts a possibility they won't have to survive.

I didn't understand this until I watched myself do it. Standing in my bedroom at midnight before an early flight, holding a sweater I didn't need, trying to decide. I put it in the bag. Then I put in another one. And I felt better. Not because I was logical. Because I was soothing something that logic couldn't reach.

6. They trust themselves more than they trust the world

Stores in other cities might be closed. They might not have the right size. They might not exist at all.

The hotel's "we have everything you need" has let them down before. The friend who said "don't worry, I packed extra" forgot their own charger, let alone a spare.

Their suitcase never closes early. It never runs out of stock. It never looks at them like they're being difficult.

Research has found that people often rely on personal possessions as a buffer against unfamiliar environments. The overpacker isn't controlling the world. They're controlling the one thing they can—the bag they packed themselves.

7. Forgetting something feels like failing at adulthood

Not remembering the phone charger isn't an inconvenience.

It's proof.

Proof that they're childish. Irresponsible. The kind of person who can't keep track of their own life. The forgotten item becomes evidence in a case they've been building against themselves for years.

I've watched otherwise competent adults spiral over a missing toothbrush. Not because they couldn't buy another one. Because the act of forgetting confirmed something they already believed, that everyone else has it together, and they're just pretending.

The extra items aren't preparation. They're armor against the shame of being caught without.

8. They believe that their comfort is their problem to solve

They don't expect the environment to accommodate them.

They don't expect travel companions to adjust.

If they're cold, it's their fault for not bringing the third jacket. If they're bored, they should have packed a book. If they're uncomfortable, that's on them.

So they carry the burden instead—in their suitcase, on their shoulder, through the airport, up the hotel stairs.

The weight is real. But it's lighter than the weight of feeling like a problem.

10. They pack for the person they wish they were on vacation

The version who wakes up at 6 a.m. for a run on the beach.

Who reads philosophy books by the pool.

Who wears silk scarves and drinks wine they can't pronounce.

They aren't packing for who they are right now. They're packing for who they want to become in a place where no one knows them yet. The running shoes that won't leave the hotel room. The novel that won't get past chapter two. The journal that stays blank.

I've done this on every trip I've ever taken. Packed for a version of myself that doesn't exist. And every time, standing in the hotel room at the end of the trip, looking at the unworn outfits and unread books, I feel a small sadness. Not because I failed. Because I wanted so badly to be her. And the suitcase was the only place she ever really lived.
