One of the reasons I started research in this area is because I feel very passionately about access to the highest level of health care. It is a very peculiar situation we're in, whereby the treatment of choice and the treatment that has the strongest evidence of effectiveness is generally not available.
If you're looking at access to medication for a mental health condition, you can probably secure that within a week. If you're looking for publicly funded talk therapy that's evidence-based, you're probably looking at a year or more.
