Trying to heal my depression naturally

I recently read a book that helped me a lot with my depression. I think the main point of it was really helpful. That the sufferer should first and foremost seek help and then take an active approach to make sure that they are healing along with finding a partner to help them on their journey. Also, it kind of opened my eyes to the different foods that can really worsen people's depression because of the different chemicals in the foods and how they can affect you. I know it doesn't seem like it but what I've discovered is that the little things all add up and can have a big impact on the way you feel. The name of the book was 'you can cure your depression' by the way.

Main things readers will learn by reading (taken from Amazon description of book):

-What nutritional supplements you can take to improve your brain chemistry naturally.
-The physical and mental activities that can lift your mood immediately.
-You'll see exactly how you can put your body into action to "re-wire" your brain to be positive naturally.
-Learn habit patterns that ensure that you will break the cycle of depression that plagues you.
-How your thoughts can be your biggest ally or a fearsome enemy, and the specific things you can do to improve your thoughts and as a result your depression.
-What foods that many Americans eat every day actually tear down your brain cells' ability to be normal and tear down your ability to be happy.
-How the way you move your body directly affects how you feel and action steps you can take to improve it, now!

I have read many of these books and tried to use the ideas but I really think that the only way to feel better is through medication or accepting the feeling and not giving it a chance to take over your thoughts and life.
