Cookie, naturopathy is not new, in actual fact, naturopathy was around before current medicine was. The only difference now is, is that current medicine started of exceeding some parts of naturopathy, but has now gotten more about money than healing, where naturopathy has now surpassed prescription type medications in most areas, though not all.
The best means to find a naturopath within your area, is to find an acupuncturist, because they will often deal in chinese medicine, a form of naturopathy, but they will generally be in touch and know who is a naturopath within your local region. Ring several if need be, but more often than not, they are generally known to all naturopaths locally. Ring them and they will help you... even book yourself in with them for an assessment for major depression, and I will put a guarantee down that you have a 99% chance walking away feeling better the next day than what you did when you walked into an acupuncturist. I say that, because often you need to sleep first and the next day shows the results. They are very very good. If I didn't rate this stuff cookie, I wouldn't bother recommending it.
It is great that you have looked, now you just most likely need to make a phone call or two, and you will soon enough have appointments. Please be straight with them over the phone, in that you have major depression, suicidal ideation and all the medication your currently on, so they can already be developing a plan of attack for you when you hit the office.
