ADHD in Teenage Girls: Why Confidence Drops in the Teen Years

For many parents, this change is subtle at first.

There isn’t always a clear moment where things shift. It’s more something you begin to notice over time.

She seems a little less sure of herself. A little more hesitant. Perhaps more withdrawn, or more critical of herself than she used to be.

And you find yourself wondering what’s changed.

The teenage years are a time when identity becomes more central. There’s more awareness of how you compare to others, more pressure to meet expectations, and more attention on performance, both academically and socially.

For girls with ADHD, this stage can bring particular challenges.

Many have spent earlier years finding ways to manage or mask their difficulties. They may have worked hard to keep up, to appear organised, to fit in. But as the demands increase, those strategies often become harder to sustain.

What once felt manageable can start to feel exhausting.

At the same time, the gap between themselves and their peers can become more visible. They may notice that others seem to manage things more easily. That they can stay on top of work, remember deadlines, organise themselves in ways that feel out of reach.

Over time, this comparison can start to shape how they see themselves.

Instead of recognising that they are working with a different set of challenges, many girls begin to internalise the idea that they are the problem. That they are not trying hard enough, not capable enough, not as good as others.

Confidence doesn’t usually disappear all at once. It tends to erode gradually, through repeated experiences that reinforce that narrative.

This is why rebuilding confidence isn’t about simply encouraging them or telling them they can do it. It’s about creating experiences where they can begin to see themselves differently.

That might mean environments where they feel understood, where they are not constantly comparing themselves, and where success is defined in a way that feels achievable and meaningful.

It also means helping them understand how their brain works, so they can begin to separate who they are from the challenges they experience.

As a parent, it can be difficult to watch this shift. You remember who she was before, or at least how she seemed. But that version of her isn’t gone.

She’s still there, navigating a stage that is asking more of her than the systems around her are currently supporting.

With the right kind of support, confidence can be rebuilt in a way that feels more stable and grounded.

If this is something you’re noticing in your daughter, you’re not alone in it. Many parents of teenage girls with ADHD see this same pattern emerge.

If it would feel helpful to explore support that focuses on confidence, identity, and emotional steadiness, you’re welcome to join the interest list for upcoming group coaching.
