In my experience it worked wonders, my chap really struggled with anxiety, crowds buying things in shops anything like that was off the cards total panic he’d go sit in the car or just refuse to go out at all made school very tough for him terrible self esteem. Full disclosure I found it really tough to deal with and made some mistakes in how I did things and trying to help. We love him and think he’s brill so I couldn’t see where this all came from, and needed to “fix” things for him ( I know now… I know!!) .
We found a psychologist who worked with him and us And it’s transformed him, he’s a happy healthy chap, he’s got insight and tools to deal with his anx, as do we and I’ve learned a huge amount from the process and changed how I dealt with things. Transformative is how I’d describe it and I’m not exaggerating so I’d say try it.
The key was finding someone who clicked with him, and we were lucky in this regard.
There may be access to help via the GP the CAMHs team or Barnardos have some support available in some areas so could be worth a try too?
Best of luck to you all.
