here in america we have just changed to a new standard of treatment and diagnosis process. self reporting is now part of the process and is perfectly ok. example if you read the DSM 5 ( which is the standard american treatment providers go by now) ,you will find the words....

These signs and symptoms may be observed by others or reported by the individual.....as part of the diagnostic criteria of mental disorders.

even when an american goes to the medical doctor self reported symptoms is a huge part of the diagnostic process..

here in america we have freedoms, rights and are part of the diagnostic process, unless a court of law has appointed another person to do that for us like children have their parents, those who have been through the court system about their abilities may have a guardian, lawyer or social worker that takes care of their mental or physical health decisions. but otherwise americans are now part of the process and their self reporting on their symptoms is now part of it too.

here in america the belief system is that treatment providers can not mind read....they cant know a person is having hallucinations if the patient doesnt self report by saying I see things, they cant know a person is having depression symptoms if the patient doesnt say ...Im so sad all the time, Ive lost interest in doing what I usually enjoy, ...the treatment provider can not mind read and know if a person is hearing voices, spacing off, losing tract of time if the patent doesnt self report by saying I hear voices, yesterday I kept losing track of time and kept spacing off...

I know Europe (where your profile says you are located) sometimes does things differently then america which is probably why our two countries differ on whether a persons self reported symptoms are part of the process of discovering how and why a persons medical and physical health problems/ behavior and what not is the way it is.
