I worked Step 4 myself, talked it over with my sponsor who happens to live in another town in my state, but I only use her as a soundboard. I used the Al-Anon resources and worked through everything myself.
I did 5 & 6 on my own, too, and then read it all to my therapist at the time. He was great helping my connect some dots and rephrase it all. Everything else I have done on my own.
I would do what feels comfortable for you, and not worry about doing what is right by the program, or any program for that matter!
