child with bipolar- poss parasites??

I am a 31 year old single mom and always sick. Flu symptoms at least for one weekend a month and headaches/ sinus pain/ allergies constantly.
Also, I have an eight year old who is diagnosed as manic depressive but I think it is something deeper. I am constantly pushed by educators and other 'professionals' like doctors to try him on all different meds, and usually many at a time. they say it is a matter of getting the right combonation. a lot of these meds are not even tested for long term safety or in kids. i am always trying to learn more to try to help my son heal holistically. he presents with frequent fever, very large cold sores, hyperactivity, Acne like skin rash on his tummy and horrible mood swings and obsessive thoughts. he is also terribly impulsive. i have read that hyperactivity is food allergy related, even in western medical journals. but i can not sustain food elimination with him because he becomes extremely violent. i feel like it is like there is an animal in him controlling him and have tried candida cleanses extensively to no relief. i have spent hundreds on herbalists/ naturopaths and got nothing useful - they never even did a saliva/ stool/ urine test. i want to find one who will or a way to do it myself. i am wondering how to try a colon/ kidney/ parasite/liver cleanse on him while i do one on me, because if it is parasites we will both need to address it, right?? I am unsure of the order and the amounts for a child, though. Also, how do I find a homeopath/ naturopath that will do the tests for me in my area? Any advice useful! thanks!
