I have been in an unhealthy codepdendant relationship with my partner since kids for 13 years and in marriage for 1. She seperated and we are going to divorce

During that time, I struggle with depression, anxiety, social anxiety and very introverted. I have no friends and distant from family.

Does anyone have tips, books, resources that help teach someone in my condition to be independent?

I am already aware of - reaching out to family - attending meetups, social outings to make friends - giving it time etc

Just wondering if anyone has used any other resources that really helped them

I also have a dog

Thank you
