Shall I tell a self diagnosis of a mental illness to a doctor? - self diagnosis more condition_symptoms

In going to the doctor this Friday for me, and I wonder what to do when I go into what seems to move a little.
Is it right to propose to my self-diagnosis for him when he was a psychological problem?
Or should indicate my symptoms without the disease, I think that is?
