Re: Hear Voices/Internal Dialogue and See things
Most of mental illnesses started to surface in late teens or early 20'. If you are in that age category, you might be experiencing mental illness. Also, terrible insomnia can not be ignored, particularly it occurs on daily basis. Besides, most of folks with mental illnesses have terrible insomnia issue.
Sounds to me like you've been having pyschotic or related issues that appear not yet be serious, .... but often without treatment/med., mental illnesses, particularly serious form of mental illness, such as Schizophrenia and Bipolar progress even within few months' period.
If it were me, I'd seek at least a Psycho-therapist working with psychiatrist, because he/she determines what form of mental illness you've been having. Afterwards, you need to see the pychiatrist who prescribes proper medication/meds. to alleviate the symptoms.
