When nothing is working: How to turn around teen behaviour in 90 days - Restore stability and rebuild connection at home

I’m Pei-I Yang — Family and Systemic Psychotherapist, and specialist in parenting & teen behaviour during the hardest chapters. For over 30 years, I’ve worked with families facing moments they never imagined:


when their teen becomes unreachable,
when every conversation turns into conflict or another aggressive episode
when home starts to feel like a battleground, battling about going to school on a daily basis.

when their teen starts hurt themselves or uses drug and alochol 

Many of the parents I support are holding everything — a demanding career, a fragile relationship, and a child they barely recognise.


They’ve tried everything. They’re exhausted. And they’re terrified this is just how it is now.

I help families step out of survival mode.

My approach blends therapeutic depth with practical coaching — grounded in child development, psychology, psychoanalysis and systems work — so you can move from crisis and shutdown to calm, clarity, and connection that lasts.

Because this isn’t about fixing your child. It’s about finding your way back to each other.

This Masterclass Showed You What’s Possible—But Watching Won’t Change Your Teen’s Behaviour.

By now, you already know:

This isn’t “just a phase.”
This isn’t “just teen behaviour.”
And this isn’t going to fix itself.

You’ve tried therapy.
You’ve stayed calm.
You’ve read the books, listened to the podcasts, followed the advice.

And still— the aggression, the shutdown, the defiance, the school refusal, the substance use, the constant eggshells…
They keep coming. 
That’s because behaviour is only the symptom.


And no one has shown you how to change the system driving it.

You Can't Keep Waiting. It's Not an Option.

A Traumatic event nearly broke the family. After a  year of trying everything but nothing worked, they found their harmony

I was really struggling to be honest! Some things happened and I lost all of my confidence. I made mistakes and didn't know how to get back on track.

 

BUT after just a couple of sessions with Pei-I, I’m feeling soooo much better. I’m really positive about the future instead of worrying all of the time. For me, the best thing has been the clear strategies you’ve provided.

And I can see the strategies you’ve given me are working already!! After just a couple of weeks things have improved massively. I’m so happy I found you and so excited for the future!! This is exactly what we needed. I know we will all be less stressed and happier because of the work we’ve been doing together Pei-I - we already are (but I’m not letting you go anywhere just yet ).

 

Anyone who is thinking of working with you should absolutely DO IT. You’re extremely knowledgeable in this area and definitely a talented coach. I feel like to always listen but equally have a lot of amazing insights to share. I love that in a coach.  Mum from England
