Struggling to Schedule ADHD Assessment

So a couple months ago, my therapist told me I likely have ADHD based on our conversations and so I asked my psychiatrist at my appointment if I could have the official assessment done. She told me to schedule with the people at the practice who are in charge of doing those assessments. It’s been months now where I keep getting distracted when I intend to call them and put it aside for another day. My husband and I joke that this alone should prove I have it. 😂
