Miranda, I agree with you.... you're smart to get it, even though it hurts to see the budget item. Like Choices and SirSavesAlot say, you are protecting your stash. You are also protecting your most important asset: your future self.
For what it's worth, and maybe to make it not seem "so bad": for 2017, the lowest price Bronze plan available for my husband and I in our state (Kansas) at ages 63 and 61 is $1419.10 per month for the two of us, together, so $709.65 each.
Prior to the Affordable Care Act, we paid over $2000 per month for the two of us for coverage....so while the current insurance options are hardly "affordable", they are less expensive than what was available before.
Just remember: YOU (present and future) are the asset worth protecting as well as you reasonably can.
