If you thought finally getting your autism or ADHD diagnosis would feel like pure relief… and instead you feel exhausted, foggy, emotional or completely flattened… this one’s for you.

In this solo episode of Autism, ADHD and Us Three, Jenny breaks down something nobody really warns you about. The post-diagnosis crash.

She explains why so many late-diagnosed neurodivergent adults experience burnout after finally getting answers, and why this isn’t weakness, regression or you not coping well enough. It is physiology.

Jenny explores what happens inside the nervous system after decades of masking, hypervigilance and pushing through environments that were never built for your brain. She talks about the relief that comes with diagnosis, and why that relief can actually trigger shutdown, exhaustion and emotional fallout.

Inside this episode:

• Why diagnosis can act like a circuit breaker for your nervous system
• How ADHD hyperfocus and autistic deep processing can accelerate burnout
• The physical signs of nervous system recalibration
• Why you cannot “optimise” your way out of this phase
• Practical ways to stabilise when everything feels too much
• What real recovery actually looks like

This episode is a permission slip to slow down. To stop turning yourself into a project. To let your body land after years of survival mode.

If you are in that shaky “who am I now?” space… you are not alone.
