Managing Overwhelm During Cancer Care

If you’re going through cancer treatment and finding everything harder to keep up with than you expected, you’re not imagining it, nor are you alone.

Many people are surprised by how overwhelming treatment feels. It’s not just the physical side effects. It’s the mental load that builds quietly in the background.

Why treatment feels so overwhelming

Coming to terms with the Cancer diagnosis places a huge demand on the brain at the same time as the body is under stress.

People often experience:

• brain fog or trouble concentrating

• difficulty remembering conversations or instructions

• fatigue that affects focus and motivation

• emotional overload or anxiety

• information overload from appointments, tests, and new terminology

It's also worth noting, for carers, this mental load can be just as heavy, often while juggling work, family, and everyday life alongside a loved one’s care.

All of this is common. And there are ways to make it feel more manageable.

Simple ways to reduce the mental load

1. Take the pressure off your memory

Stress, fatigue, and treatment side effects can all affect memory. Write things down! Appointments, symptoms, medications, or questions. Writing it down means you don’t have to hold everything in your head.

This can help both patients and carers feel less anxious about forgetting something important.

2. Keep everything in one place

When information is spread across notes, phone messages, Dr's appointment cards, emails, and scraps of paper, it adds to overwhelm.

Having one place to record appointments, treatments, symptoms, and notes can bring structure during an otherwise uncertain time.

3. Prepare for appointments

It’s very common to think of questions after an appointment ends.

Jotting questions down as they arise and recording answers during visits can help appointments feel clearer and more productive, especially when energy or concentration is low. 

This can be particularly helpful when carers attend appointments or help take notes during discussions.

4. Track symptoms over time

Side effects can change gradually, or with changes in treatment. Brief notes as symptoms occur can help identify patterns and make it easier to explain what’s been happening to the care team.

Clear records can support better day-to-day management and follow-up care.

5. Go at your own pace

Some days you may use tools or write things down. Other days you may not. Both are okay.

Support tools are there to reduce pressure, not add another task.

A note from nurses

As nurses, we see how disorienting cancer treatment can feel, especially early on. Patients and carers often tell us they feel overwhelmed not because they aren’t coping, but because there are simply too many unfamiliar things to manage at once.

Reducing the mental load can help people feel steadier, more prepared, and less alone during treatment.

If you’d like extra support

If you think having a practical tool to hold everything related to treatment in one place could help for you or for someone you’re caring for, you can learn more about the CanPlan Cancer Planner here.

It’s designed to support patients and carers by helping organise appointments, track symptoms and medications, prepare questions, and record important information all in one place. It also includes optional wellbeing prompts and exercises that some people find comforting or grounding during treatment.

There’s no right or wrong way to use a tool like this.
