I have found that writing down or making a list on your phone of what you feel you need help with the most can be super helpful, because when I get in there my mind always just blanks. Also they will likely ask you a broad range of questions to evaluate you, so just be honest and try your best to explain what you’re feeling clearly. Don’t be afraid to ask questions and take note in your phone of anything they tell you that you feel you will want to remember.
