Why Do Small Decisions Feel So Hard? Decision Fatigue, ADHD and Wedding Planning
By Shannon Graham, CCC, ADHD-CCSP, Calgary
It's 9 p.m. You've been meaning to "just knock out a few wedding things" since last night. Now you have 14 tabs open, two group chats going, and a Pinterest board that has somehow grown to 300 pins.
The question in front of you is napkins. Ivory or eggshell? Eggshell or champagne? You zoom in, zoom out, and ask your partner, who says "whatever you think." Not helpful.
So you close the laptop, having decided nothing, and somehow feel more tired than when you started.
If that sounds familiar, nothing is wrong with you. This might be decision fatigue, and if you have ADHD, or you're carrying a lot of other people's expectations, it can hit even harder.
This is week one of a six-week series where I'm using wedding planning to talk about executive function and boundaries. If you're not planning a wedding, stay with me. The same patterns show up when you move, have a baby, change careers, or go through any stretch of life that asks you to make a lot of decisions quickly.
What is decision fatigue?
Decision fatigue is that worn-out, foggy feeling that builds when you make a lot of choices in a row. You might put things off, pick whatever's easiest, or shut down when the next person asks you about chair covers.
Even a small decision asks a lot of your brain. You have to hold the options in mind, compare them, imagine how each one might turn out, and guess how other people will react.
One napkin decision is fine. Wedding planning stacks hundreds of them on top of the life you were already managing: work, bills, laundry, the dog's vet appointment. No single choice is the problem. The problem is that the choices don't stop.
Why it can feel harder with ADHD
ADHD involves differences in executive function, the brain skills that help you plan, prioritize, get started and keep information in mind. Decisions rely on almost all of them.
I like to think of executive function as your brain's front desk. It sorts what needs attention now, what can wait and what can go straight in the recycling. With ADHD, the front desk is often short-staffed, and every piece of mail shows up marked urgent.
In wedding planning, that might look like:
● Everything feeling equally important, so napkins take as much energy as the venue
● Struggling to compare five photographers, because keeping prices, styles and dates in your head at once leans on working memory
● Knowing exactly what you need to decide and still not being able to start ● "Six months away" feeling like forever, until it suddenly feels like next week
That stuck feeling is often your nervous system hitting pause, not a lack of willpower or a sign you don't care about your own wedding. It's how your brain handles information, and once you can see that, you can build support around it instead of blaming yourself.
The invisible committee
Most wedding decisions don't happen on their own.
You think you're choosing a guest list. But you're also choosing how your mom will feel, what your aunt might say at Thanksgiving, whether your partner's family will think you're being difficult, and how it'll look online.
I call this the invisible committee. It doesn't have a seat at the table, but it has an opinion on everything, and every reaction you try to predict adds weight to the decision.
So if a "simple" choice leaves you completely drained, it might not be the choice. You may have been quietly trying to keep six people happy at once.
We'll come back to the committee later in the series, because figuring out who actually gets a vote makes a big difference.
Why a full brain makes boundaries harder
This whole series is built on one idea: it's hard to hold a boundary when your brain is already full.
A boundary is a decision too. Saying "we're keeping it under 80 guests" or "I can't talk about the wedding tonight" takes planning, the right words, and enough steadiness to handle someone's reaction. That draws on the same energy all those other decisions have been using up.
So when you're at capacity, you take the path with the least friction. You say yes, go along with it, and plan to deal with it later. Each yes adds something else to carry, which leaves even less room for the next no.
Overwhelm and resentment are signals
Two feelings tend to show up when a boundary is missing:
● Overwhelm ("I can't keep track of all of this") often means you're holding things that could be shared, handed off or dropped.
● Resentment ("Why am I the only one who…?") often means you said yes to something you never really agreed to.
Neither one means you're doing this wrong. For this week, just notice when they come up and what you were doing at the time.
Five ways to make fewer, “better” decisions
The goal isn't to become a perfect decision-maker. It's to stop making every decision from scratch, so your energy goes to the parts you'll actually remember.
1. Pick your top three. You and your partner each name the three parts of the day you care about most. Maybe that's the food, the music and your first dance. Those get your time. Try to tolerate some things being good enough.
2. Shrink the options. Ask vendors, friends, or your own search to give you two or three choices, not twenty. If it's not on the short list, it's not in the running.
3. Make a rule once. For example: "If it's not in our top three and it's within budget, the first good option wins." Write it somewhere you'll see it.
4. Decide who gets a vote before you ask. Before opening the family group chat, get clear on whose input is advice and whose is an actual vote. Opinions are much easier to hear when you already know what you'll do with them.
5. Choose when you choose. For most people, 10 p.m. isn't a great time. Set aside a short block, like 30 minutes on Saturday morning, and let yourself close the tabs the rest of the week.
If you have ADHD, a few extras can help: set a timer for each decision, make choices with someone else in the room (body doubling), and keep one running list of what's already decided so you're not holding it all in your head.
Not planning a wedding?
Weddings are just a loud example. The same pile-up happens when you're moving and every box is a keep-or-toss decision, when you have a new baby and every product and schedule needs a verdict; when you're changing careers, or when you're caring for a parent while running your own household.
When the decisions never let up, it can turn into burnout: feeling depleted, short-fused and like you're on autopilot. Swap "napkins" for "daycare" or "which job offer," and the five ideas above still work.
When it might be more than decision fatigue
A rough week of wedding admin is normal. It may be worth talking to someone if:
● you feel stuck, foggy or overwhelmed most days, not just planning days
● small decisions bring up a lot of anxiety, guilt or fear of getting it wrong
● you're snapping at the people you love, or pulling away from them
● you've wondered for a while whether ADHD might be part of the picture
Counselling can be a place to sort out what's yours to carry and what isn't, and to build decision-making support that fits how your brain works.
