I'm so sorry for your loss, anon, may God bless you and give you peace!
A couple years ago I heard an interview with a doctor or other medical expert against GMO's. Pretty sure it was on Infowars. The discussion got very technical, but I know she said new research showed that GMO's somehow latch onto our DNA, and can actually alter it permanently. Her point was, you can't "just" stop eating GMO crap and expect everything to go totally back to normal again.
Damn, I wish I could remember who she was…
