ADHD and Waiting Mode: Why One Appointment Can Take Over Your Whole Day

Have you ever had an appointment at 3pm and found yourself achieving very little before then?

You know there's plenty of time to get things done, yet starting anything feels surprisingly difficult. Instead, you find yourself checking the clock, thinking about the appointment, or worrying you'll lose track of time and miss it altogether.

Many adults with ADHD describe this experience, often referring to it as waiting mode.

Although waiting mode isn't an official clinical term, it is something I hear about regularly from clients and have experienced myself.

What Is Waiting Mode?

Waiting mode describes the feeling that an upcoming event takes over your attention, even when it isn't happening for several hours.

It could be a meeting, a parcel delivery, a phone call, or an appointment. Rather than getting on with your day, your brain seems to keep returning to the fact that something important is coming up.

As a result, you may avoid starting larger tasks, repeatedly check the time, or feel unable to relax because you're worried you'll forget where you need to be.

Why Does It Happen?

For many people with ADHD, this comes back to executive functioning and working memory.

Keeping track of future events requires mental effort; rather than trusting that you'll remember, your brain keeps bringing the appointment back into your attention so it doesn't get missed.

Unfortunately, that constant mental reminder can make it much harder to fully engage with whatever you're trying to do in the meantime.

It's not laziness or poor motivation - your attention is simply being pulled towards something your brain has decided is important.

What Can I Do?

There isn't one solution that works for everyone, but there are several strategies that many people find helpful:

• Set reminders that you genuinely trust, so your brain doesn't feel the need to keep checking.

• Write appointments somewhere visible rather than relying on memory alone.

• Break work into smaller tasks that can be completed before you need to leave.

• If you have a longer project to work on, set yourself a clear finishing time so you don't worry about losing track of time.

• If possible, avoid scheduling non-urgent appointments in the middle of the day, as they can interrupt your momentum.

You're Not Just "Bad at Managing Time"

One of the biggest frustrations with waiting mode is that people often blame themselves for wasting half the day.

In reality, many adults with ADHD are working incredibly hard just to keep that upcoming commitment in mind. Recognising why this happens is often the first step towards managing it more effectively.

I've certainly caught myself doing this over the years; an appointment later in the day used to make it feel as though I couldn't properly settle into anything beforehand. Understanding why this was happening helped me stop blaming myself and start putting simple strategies in place instead.

Having something important later doesn't have to mean the rest of your day is lost. The goal isn't to ignore the appointment altogether, but to trust yourself enough that you can get on with your day until it's time to leave.
