I was told by my new counselor that i am on the spectrum for schizophrenia. she didnt diagnose me with that. what does that mean and i thought diagnosis for that are late teens early 20s?

Yes, younger folks are more often afflicted, but there are several variations of schizophrenia, and to be reassured, do have a full psychiatric consultation to clarify what you really have.

Spectrum is just a clinical term that implies that the person is in the wide range of possible expressions of a disorder/condition. The late teen and early adult years are a common time for the disorder to appear, but these people get older with time and their symptoms may evolve to be more or less intense. You need to clarify with your counselor how they use the term.
