In some way I experienced the same crap you experienced for 6 years while living in Toronto (Canada), as you might know by now pretty much all the food you can get in north America is full of toxins unless eating organic food 100%, eating junk food for almost 4 years, and believing on allopathic doctors which they have basically turned into Pharmaceutical labs extension, prescribing all sort of drugs carelessly and using us as a guinea pigs, as a result I ended up on the crazy cleaning frenzy you were as I got very sick.
I did Chelation for like a year with heavy stuff like DMSA, ALA. At least 10 liver flush, probably 20 colonics, actually at one point to get my bowel movements I was relaying only on them, and my life was turning into a nightmare as the problem was not about cleaning which at one point might help the bottom line is called balance, body and mind balance.
As I exhausted everything, from allopathic to naturopathic doctors and all kind of doctors wasting tons of dollars with them, finally I went into Chinese medicine and since then I am a different person.
Chinese medicine is the only medicine in the world and the most ancient one, that really care about you, as they look into balancing you.
As a matter of fact I went once to my Chinese doctor asking about what to eat and he told me I should eat everything as life and balance is based on 5 elements which have five different tastes sweet, salty, sour, bitter and pungent, too much on one of them and will create and unbalance as a result sickness, this is based on eating habits. On the other hand the problem is also about reestablishing the lost balance and this can be achieved with herbal teas prescribed by Chinese doctors and also with acupuncture plus tons of exercise as the problem is energy not flowing free on your 12 meridians.
So please no more cleaning for at least one year, let your body to settle down, focus to balance your mind and body with the help, of Chinese medicine, acupuncture, chi gong, and exercise. Get plenty of sun and fun. From this point you have to focus in your main concerns and starting to build up your endurance from there.
Don’t lost the faith you will overcome your unbalance and will find the light at the end of the tunnel, if you need more guidence just let me know I will help you,
