Can see a doctor instead of a therapist to get help for anxiety?

Anxiety: The choice is yours. Any professional with knowledge about cognitive behavior therapy, can help.

Yes: Psychiatrists are doctors who may offer both psychotherapy and prescribe medications as needed. Not all do the psychotherapy part, but it's a very important way of helping with anxiety. Most primary care doctors prescribe medications, but do not offer psychotherapy at all. You can choose the type of treatment you want, but have the best chance of healing anxiety by getting to its heart.

Sure: Primary care doctors treat simple anxiety all the time. Of course, this often means prescription tranquilizers — safe & effective if used rarely, not good if used often. Some will prescribe ssris or other meds instead; every option has pros & cons. In contrast, psychotherapy may more successfully get to the cause of the anxiety, to prevent it from returning. And there's no addiction risk.
