Talk therapy is a pretty general term. Just means you go and talk and they listen. Within talk therapy there is cognitive behavioral therapy, DBT, EFT/EMDR. There's a lot of different stuff out there, i'm sure whoever you're seeing specializes in something but the specification doesn't really matter in your situation I don't think. I bet it'll be just talking and listening and the therapist getting to the root of the issue through questions. It might be intimidating, but I think you'll find it helpful in the long run.
