@SarahGen-- Many health insurance companies charge higher co-payments for mental health problems. This has been the case even though there is a law that says that mental health has to be treated equally to physical illness. I think the government is working on this though, they are trying to make insurance companies comply with the law.
I actually can't blame the insurance companies entirely because they are businesses that are trying to make money. Some mental illnesses are not curable and chronic which means that the patient needs constant care. That means a lot of money for the insurance company and that's why they try to avoid it.
I guess this is where government public health policies come in. The government needs to have special programs/insurance available for patients with mental illness.
