It's okay to ask for structure or direction. Also, I often e-mail my therapist a thought about something I want to bring up but am sure I WON'T. She does a great job of bringing it up for me, then letting me know it's still my choice if I want to talk about it. Or maybe you could write a few things down through the week and give to your therapist. I tend to space out easily (talk therapy just wasn't even worth it for me...doing somatic/body psychotherapy), but it's been helpful to stick through the difficult points and ask my therapist for more direction sometimes.
