hello and welcome.
I'm so sorry to read how you are struggling with your 13-year-old's anxiety and returning to school. Unfortunately I am not away of any groups. Perhaps the psychologist might know? In your post you also mentioned things are falling apart quicker than ... I hope you don't mind my asking (and please do not feel that you have to answer and) what sort of things are the happening in terms of falling apart?
On the plus side ... it's great that you have a psychologist working with your teen. However, I know first-hand how slowly progress can feel when you're in the middle of the turmoil. (I know this is a different situation to what you are going through, but when I started getting help for myself, I was hoping for a timeline when things would get better.) Please don't lose hope - with professional support and your loving guidance, things can and will improve over time.
In the meantime, try to make some time to practice self-care for yourself and others in the family. The calmer and more grounded you can be, the better you can weather the storms. What sort of support do you h have in terms of terms of family or friends for emotional support?
One day at a time, with help and care for the whole family, I hope you'll start to see the light at the end of the tunnel.
Listening...
