    Spent no time discussing different care plans, barely looked at my skin, did not ask for a history. Interrupted me, dismissed my concerns. I was extremely frustrated that I waited for this appointment for over a month and it was finished in under ten minutes with me having little to no understanding of the medicines I was prescribed.
