From my research, once you get rid of the parasites, you will get rid of diabetes. I am no doctor, so I don't claim to know this 100%, but from what I have read from Dr. Clark, this is the case.
I also recommend a book from http://www.docsutter.com, The Paradigm Shift in Health Care. His book outlines what you should do to get healthy and stay healthy. Buy it, you won't regret it ... I can tell you need help by your post.
The order of the protocol is colon cleanse, parasite cleanse, liver flush.
He will let you know what to do with each cleanse.
He continually says, detox, detox, detox. And I see where you said you eat clean, but we can still ingest heavy metals, parasites from fresh foods from all the pesticides, etc.
Never do a Liver Flush before a parasite cleanse, it causes many problems from what I have read and heard.
I hope this helps ... his book is one of the best I have read about getting healthy.
