Suggest Treatment For Depression,anxiety And Eating Disorder

I have been suffering from mental health problems for the past year, I have left college and work and am under the care of the community mental health team. I have been diagnosed with depression and anxiety, but I feel like they are missing something. My CPN doesnt seam too bothered that I tend to swing between symptoms of anorexia and over eating, even though in the past I have had an eating disorder, and since I went to my doctor with depression a year ago I havent seen a psychiatrist, apart from a duty one in A&E after a overdose. Do you think it unreasonable to want to see one?
