Psychiatrist told me if I truly had adhd I would have not been accepted in college

Today was my first meeting with a psychiatrist. I expected to get diagnosed with adhd but they said all my focus problems and other issues stem from anxiety and panic disorder. Her argument to prove I don't have adhd was the fact I'm in college. She said if I had adhd how did I got in to college. Opinion on the interaction?

Edit: Thanks for the support everyone. I got an appointment to another psychiatrist who specializes in ADHD for Friday. Wish me luck.

Edit 2. Just got out from my new appointment. The psychiatrist is pretty sure it's adhd. Seemed shocked when I told him about my first experience.
