The link between pesticides and anxiety/depression

I have been doing a lot of research over the past few days, trying to find out what other routes I could take to lessen my daily anxieties: seeing another psychotherapist, seeing a Naturopathic Doctor, hypnosis, acupuncture...a myriad of things. I wanted to check out everything and anything that could help me. Then I stumbled upon one therapist in Toronto that usually asks her anxiety/depression clients about their diet...to which she recommends they try a diet full of organic foods and in short periods of time they start to feel a lot better. So I continued on this path and found out that there have been links between pesticides (used in normal grocery store produce, for example) and anxiety/depression.

I've never been much of a sugar person, but sugar has also been linked to depression for years. I basically continues researching organic foods and anxiety and I'm wondering if that would help me. Although organic food here is very expensive, which is probably why I've never tried it. Have you ever eaten organic food and found that it helps you with your mood disorder? Basically, through my research I've been warned of pesticides used in produce, and to stay away from sugar, caffeine, products made of white flour, not to eat pork or margerine or drink cow's milk...it became such a long list of things I shouldn't consume that I got really frustrated. I'm not shy when it comes to trying new things (organic food, for example), I simply wanted to know if it would really be beneficial for me or just a waste of money?

I found this information to be very interesting, and I want to know if you have tried any of the things I mentioned looking up when I was conducting my research. Please leave me a comment about which one it was and how the experience is/was for you. I am seriously considering seeing a Naturopathic Doctor at least to see what they say (plus it's covered by my husband's insurance plan). I'd like to hear your story. :)
