Can also find some very useful information here:
Early Psychosis Treatment center information in these two links
Psychiatric Treatment Centers affiliated with Medical Schools in the USA
This link may help you find a psychiatrist in your area
Getting your son into an Early Intervention Program or an ACT/PACT program would probably help a lot.
A really good article on anosognosia. It’s hard for someone to see that they need help when the condition itself causes the person to not be able to see that they need help.
Some other links that may help:
I know that was a lot of information/links.
Since your son is 17 and not legally an adult yet then there are some things that you may want to start considering. So many parents/caregivers find themselves in harder situations once their loved one reaches adulthood as privacy laws come into play. Learn the privacy laws where you live.
I don’t think I have any links for this however start looking into having releases and consents signed so that you have access to your son’s files and treatment team.
