Assessment: Rather than trying to diagnose yourself, encourage you to tell all these symptoms to your medical provider, if you have not had a comprehensive psychological evaluation by a psychiatrist or a clinical psychologist - would recommend this. This will help to clarify your diagnosis -but the diagnosis may take more than a session to determine.
