Why does it suddenly feel like everyone has a diagnosis? From ADHD and autism to anxiety, trauma, burnout, and depression - mental health language is everywhere right now. But are rates actually rising? Or are more people finally being seen after years of being overlooked, misread, or excluded from the stereotype? In this episode, we unpack the psychology, politics, and culture of diagnosis: how diagnostic criteria have changed, why context matters, what social media has done to this conversation, and the tension between labels as affirming, or oversimplified. We explore:•        What the data actually says about rising diagnosis rates•        Why historically missed groups are being recognised more now•        The role of context in shaping our experiences•        The risk of pathologising ordinary human struggle•        When scepticism is useful - and why it should be aimed at systems, not individuals•        Why a label can still be meaningful, helpful, and nobody else’s business Watch on Netflix: HERE Follow Jemma on Instagram: @jemmasbeg Follow the podcast on Instagram: @thatpsychologypodcast Subscribe on Substack: @thepsychologyofyour20s For business: [email protected]  Our favourite sources: https://pmc.ncbi.nlm.nih.gov/articles/PMC7422602/https://pmc.ncbi.nlm.nih.gov/articles/PMC4810039/https://pmc.ncbi.nlm.nih.gov/articles/PMC11747871/https://pmc.ncbi.nlm.nih.gov/articles/PMC10251666/https://reference-global.com/article/10.58734/plc-2025-0009 The Psychology of your 20s is not a substitute for professional mental health help.

It can feel like the world - and our future - has never been more precarious or frightening. It’s a very normal response to feel anxious about it - and in many ways, being concerned is just a sign that you’re alive, switched on, and care about the what’s going on around you. But what happens when this anxiety becomes overwhelming, and we’re consumed by worry about the future? In this episode, we unpack: • Why we’re prone to anticipatory anxiety in our 20s• The evolutionary reasons for catastrophic thinking • Why long-term anxiety rewires our brain • When it’s healthy - and not healthy - to worry • How to rebrand anxiety as excitement Happy listening!

We are bombarded with ideas about how we should look, behave, and be. But instead of trying to constantly strive for the societal ideal, we can cut through the noise another way - and that’s by cultivating self-love. The funny thing is, psychology actually shows us that the more confident and self-loving we are, the more attractive we become. It’s a win-win… if we can get there. Today, we're going to talk about how loving ourselves makes us more attractive. We unpack: •  The power of the mind-body link and self-esteem•  Why plastic surgery might not make us happy •  The damaging physical effects of negative self-talk•  How simple behavioural changes affect how others see us•  Why cultivating self-love is the greatest gift we can give ourselves Watch on Netflix: HERE Follow Jemma on Instagram: @jemmasbeg Follow the podcast on Instagram: @thatpsychologypodcast Subscribe on Substack: @thepsychologyofyour20s For business: [email protected]  The Psychology of your 20s is not a substitute for professional mental health help.

Your 20s are sold to you as the “best years of your life” - which is hilarious, considering how many of us spend them underpaid, overthinking, heartbroken, living in transitional housing, and finding a new identity every 6 months. So what does it actually mean to ‘romanticise your 20s’? In this episode, we break down romanticising as a real psychological skill - how your brain constructs meaning, why attention shapes what feels like reality, and why building a coherent life story matters most when your life feels messy. We explore:•        Why your attention changes your experience•        The neuroscience and cognition of meaning-making•        The role of emergent adulthood•        Why narrative psychology is so important•        Five grounded ways to romanticise your life Watch on Netflix: HERE Follow Jemma on Instagram: @jemmasbeg Follow the podcast on Instagram: @thatpsychologypodcast Subscribe on Substack: @thepsychologyofyour20s For business: [email protected]  Our favourite sources: https://pmc.ncbi.nlm.nih.gov/articles/PMC4324396/https://www.tandfonline.com/doi/full/10.1080/00224545.2025.2563539https://pmc.ncbi.nlm.nih.gov/articles/PMC3045747/ The Psychology of your 20s is not a substitute for professional mental health help.
