Hello, I'd like to help you with your question.
It is common for symptoms related to Schizophrenia to show up around the age you are now, in the early 20's. While what you are experiencing may not be Schizophrenia, it is not a good idea to ignore these symptoms.
The symptoms you describe can also be part of a disorder called Paranoid personality disorder
, Schizophrenia or a psychotic break. There is also psychosis
that is related to depression that could be a possibility. Sometimes these symptoms can be persistent (without treatment) or they could be temporary, which is why it is so important that you consider getting another evaluation. If you have spoken to your current therapist and they have not done another evaluation to determine why you are having these symptoms, then you need another professionals opinion.
You may also want to explore information about your symptoms to see if you feel you match any of the possible disorders. Here are some links to help:
Once you find out what you might have, there are a number of treatment options. Medications are usually the best option for these types of symptoms because hallucinations and paranoia is thought to be biologically based. But speak with your therapist and psychiatrist for the best options for you.
I hope this has helped you,
