Sounds good - my thought is simplify: make a therapist appt and go. Be honest and lay things out and ask your questions about CBT. My psych is the one who brought it up with me. Whatever research you can do into someone you can see- ie are the categorized as someone with specialization in addiction, or CBT/DBT, or childhood trauma, or whatever might apply (we used this type of selection info when finding an in-network therapist for my step son, for example).
Like with anything- one step at a time. I know you want to figure it all out but you have proven like I did in my attempts that I can't tackle all of it at once; starting with an appt, or a sober day, or a next right choice, and going from there is the path I have found to staying sober so far.
