My psychiatrist laughs at me when I try to explain my symptoms

Pretty much the title. Every time I try to explain what I’ve been experiencing or my symptoms, my psychiatrist just laughs at me. I have been on medication for the past few months and they haven’t helped. I try to tell him that but I feel he just invalidates me. I told him I am better in a crisis but suffer from executive dysfunction otherwise, he simply said, “I do believe you but I don’t understand your symptoms. “ I don’t know how to communicate and get the help I need.
