I read Bradshaw too but it has been years. I am also not big into org religion. Brenė Brown is agnostic in her work. She certifies therapists to teach it and there are intensives and workshops you can take. There is a directory on her site. My T is certified and sometimes does free stuff. There are only a few like her in my area but they have discussed some sort of ongoing group after the workshop as more people take it.

DBT is another option to look into. The founder, Marsha linehan, is both religion and treatment agnostic. She is spiritual just doesn't care what you are. Those classes are all over the place and it is worth it to do you research about the facility though I don't have much advice on that. I ended up with a great dbt therapist in a lousy facility.

They are completely different approaches so which ever is more comfortable. Both will teach you you are in fact deserving
