I want to tell you that if you live in the US, and you decide to see a doctor that is your business by law. He can't know what goes on, or even if you are a patient anywhere. You have no insurance so you may be able to get in to clinics that have sliding scales to be seen. If nothing else you can maybe find a therapist.

Everyone else is right: you don't just "get over" psychosis. And it's not shameful to have psychosis, just the meida turns it that way. The stigma is ridiculous. You don't tell people with diabetes to "just get over it," also if you had diabetes your husband couldn't "cure" that, either. It's nothing to do with him. Tell him that having his support will be better than having to live in shame over being who you are and needing help. This site has good education tools for your husband. You can print them out.
