Hey @JessT,
I'm one of the moderators on the forums. That sounds so challenging raising a teenager who has been struggling with Generalised Anxiety Disorder and Depression for some time, particularly as a sole parent. It's really understandable that stress would take it's toll, so it's great you're reaching out for support.
Welcome to the forums I hope you find them really helpful. Here are a few discussions/areas of the forums you might be interested in:
Introduce yourself here
Social spaces on the carers forums.
Looking after ourselves, where there are lots of self-care discussions.
If you are looking for a face to face support group as well Carers Australia on 1800 242 636 can help you connect with local carer supports including support groups.
Take care
