It sounds like you are perhaps searching for an answer as to why you feel the way you do, and hoping that a diagnosis will give you an answer? Seeing a therapist might help you to explore why you feel the way you do? I'm not sure that psychiatrists usually do much except give pills. As to whether your psychiatrist should have given you a diagnosis - I think sometimes they are reluctant to label people, and a good one might see a patient as an individual with unique problems that don't necessarily fit into any one diagnostic category. Hope you are doing ok.
