How do you deal with “I told you so’s?”

I really have worked hard to modify my health habits.

I know I was not eating great — and at the time, I KNEW I was not eating great — and not working out. I also felt stressed and pressed for time. I ALSO have mitigating factors in my development of D — two now — GADAs, AND Niacin (apparently I am a reactor). And I knew I was becoming obese — teetering on the edge of it, but nonetheless. I also know my habits were being driven by my blood sugar, especially just pre-dx. Heck, I sought medical help 7 or 8 mos BEFORE diagnosis, and blood sugar was one thing that was checked.

So how do you deal with the people who just have to say, "TOLJA SO!" despite being human themselves, with health habit shortcomings? What do you say? It just seems childish. I suspect misery loves company, and this person wants me to blame myself for my condition.

PS this person did, and still DOES email me telling me about their junk-food fests.
