Doctors don't really know. They think they do, but they don't.

Perhaps, your list of disorders and symptoms can be explained with another disorder that no one bothered to consider. Eg. schizoaffective disorder.

I went through a multitude of labels before I found out what was apparently wrong with me:

PTSD,
Dysthymia,
Depression,
Psychotic Depression,
Psychotic Disorder NOS, (I almost got Dx'ed with schizophrenia)
Bipolar II,
Cyclothymia, &
Borderline Personality Disorder.

I only agreed with dysthymia, depression and psychotic disorder NOS. At the time, I was a hurting teenager who wasn't very cooperative and honest with the psychiatrists so rest of these diagnoses are BS.

Most of my symptoms disappeared in my early 20s when I stopped taking medication.
