I want to say, 

> Your situation is, *without exaggerating*, more severe than mine.

However, I want to replace "without exaggerating" with an *adverb*. Something like "undoubtedly". 

Now I know the word "unexaggeratedly" has not been born yet, and that I can always use the same sentence I mentioned above, but I love using adverbs in this fashion. I'm curious to know if there's an antonym for the word "exaggeratedly".
