Anxious, possibly depressed 7yo, who do I talk to?

[aftereight]

This is a long term, ongoing issue, and has been getting worse over the last few months. I have spoken with her teacher, but think I now need to run it past a health professional. Who do I need to contact? I spoke to a HV who suggested the school nurse first rather than GP, does that sound right?
I just want my daughter to be happy and enjoy her life, rather than endure it.

This book from USA helped my very fretful and negative son. She's about the right age for it too. It just teaches them that their worries are not reality and that they can control their feelings and thoughts with practise.

I really recommend it. I still dip into it to help remind myself some ways to respond to him when he's feeling anxious.
