Ants are eating my brain, WHAT?

I went to a bachelorette party because I'm just one of the girls like that. So, Katie was telling me about this co-worker of hers...it seems his sister, whose legs fell off a few years back, woke up covered in ant bites. The ants were, from best we can gather, eating her flesh during the night. She subsequentally went insane because as it was discovered, the amount of venom was so great, it actually poisoned her brain. Did I make this up? NO! For real!
