Does anyone know of any BDD self-help materials they would recommend?

So I've never used any BDD self-help materials before because I just couldn't face it, but I've been feeling a bit better recently so I looked into it and found something.

It's a workbook called Building Body Acceptance and it's written by the CCI of Australia. And I'm really liking it so far! I've only read some of the first module and answered some of the questions on it, but it has my interest piqued and it also helped me take control of an obsessive episode I was going through.

So I just wanted to see if anyone here knew of any BDD self-help materials they've used that they'd like to share with this community.

Thank you :)

EDIT: Embedded a link to the workbook I was reading to make it easier for anyone interested to find
