Are you in school? Can you speak to a counsellor? Larger counties and cities in the States usually have community mental health sites and you’d be able to, at least, talk to someone with mental disorder experience.

If you wish to keep your parents out-of-the-loop (which I do not advise) California law provides guidelines for kids twelve or older. But there’s no guarantee that you’d qualify for that exemption. Again, I cannot stress how strongly I feel about involving your parents in your healthcare. From the very start, if possible.

The symptoms that you list could be anything. You used the words delusion, detached, disconnected and unreal. Kind of scary stuff.

Again: Parents, school, community mental health services — just talk to someone, okay?

Good luck.
