Just Diagnosed with ADHD or Autism: What Now?

You have a diagnosis. After months or years of wondering, you now have a name for the thing that's been shaping your life in ways you couldn't quite articulate. For some people, this moment feels like relief. For others, it triggers grief, anger, or a disorienting sense of 'now what?' Often it's all of these at once. Whatever you're feeling is normal. There's no correct emotional response to finding out your brain works differently from what you'd assumed.

The First Few Weeks

Give yourself time to process. A diagnosis reframes your entire personal history, and that reframing doesn't happen overnight. Many people go through a phase of re-examining their life through a new lens: the school struggles, the relationship patterns, the jobs that didn't work out, the strategies they developed without knowing why they needed them. This is valuable work, but it can also be emotionally intense. There's no rush to take action immediately.

That said, there are some practical steps worth taking early, not because they're urgent, but because the systems involved often have waiting times.

Practical Next Steps

1. 1

   Inform your GP. If you were assessed privately, send your GP a copy of the diagnostic report. This starts the process for shared care (if medication is recommended) and creates an NHS record of your diagnosis. Some GPs will want to discuss the report with you, others will simply file it. Either way, having it on your medical record matters for future support.

2. 2

   Understand your treatment options. For ADHD, NICE guideline NG87 recommends medication as a first-line treatment for adults, alongside non-pharmacological support. For autism, there's no equivalent medication pathway, but support options include specialist therapy, coaching, and workplace adjustments. Your clinician should have outlined a treatment plan in your assessment report.

3. 3

   Consider workplace support. If you're employed or self-employed, you may be eligible for Access to Work, a government grant funding up to £69,260 per year in workplace support. This can include coaching, assistive technology, a support worker, and environmental adjustments. Applications take time to process, so starting early is worthwhile.

4. 4

   Look into reasonable adjustments. Under the Equality Act 2010, your employer has a legal duty to make reasonable adjustments if your condition affects your work. You don't have to disclose immediately, but it's worth knowing your rights. Our guide on telling your employer covers the decision in detail.

5. 5

   Connect with others. Peer support from people who've been through the same experience is consistently rated as one of the most helpful post-diagnosis resources. ADHD UK and the National Autistic Society both offer online communities, local groups, and helplines.

The Emotional Arc

Most people experience a recognisable emotional pattern after diagnosis, though the timing varies enormously. The initial reaction is often relief or validation: 'So that's why.' This is frequently followed by grief for the years spent struggling without understanding or support, sometimes accompanied by anger at the systems (schools, GPs, workplaces) that missed it. Then comes a period of re-evaluation, where you revisit your past through the lens of the diagnosis. Finally, most people reach a point of integration, where the diagnosis becomes part of your self-understanding without defining everything about you.

This process can take weeks or months. Some people find therapy helpful during this period, particularly if the grief or anger phase is intense. If your diagnosis was for ADHD, ADHD-specific CBT addresses both the practical and emotional aspects. For autism, specialist counselling from a therapist who understands autistic experience (rather than one who views autism as a deficit) can be valuable.

What About Medication?

If you've been diagnosed with ADHD, medication is likely to be part of the conversation. NICE recommends lisdexamfetamine or methylphenidate as first-line treatments for adults. Medication doesn't work for everyone, but for many people it's transformative: not a cure, but a significant reduction in the effort required to do things that were previously exhausting.

The process takes time. Titration (finding the right medication and dose) typically takes 8-12 weeks. If you were assessed privately and want NHS prescribing, your clinician will need to set up a shared care agreement with your GP. Some GPs accept these readily; others are reluctant. Our guide on GP acceptance of private diagnoses covers what to do if you hit resistance.

There is no equivalent medication pathway for autism. Support focuses on therapy, environmental adjustments, and practical strategies rather than pharmacological treatment.

Things People Wish They'd Known

A diagnosis explains, it doesn't excuse. This is a distinction that matters for your own self-understanding and for how others receive the news. Understanding why you've struggled is empowering. Using the diagnosis as a reason not to address difficulties isn't. The sweet spot is using the diagnosis to inform better strategies, not to abandon the effort.

Not everyone will understand. Some people in your life will be supportive. Others will minimise the diagnosis ('everyone's a bit ADHD'), question its validity ('you seem fine to me'), or become uncomfortable. You get to choose who you tell, when, and how much detail you share.

The diagnosis is the beginning, not the end. Assessment answers the question 'what's going on?' The work of figuring out what to do about it stretches ahead. That can feel daunting, but it's also where the real benefit lies: you now have a framework for understanding yourself that makes practical support, legal protections, and funded assistance available to you.
