What Is Your Horror Story From DNA Tests Like 23andMe?

A while back, we rounded up a bunch of horror stories from people's experiences with DNA tests like 23andMe. And, it turns out, a lot of people wanted to share their similarly shocking stories. So, we want to know, do you have a wild or shocking story about taking a DNA test?

For example, maybe you found out your grandfather, who you thought died when you were just a baby, was actually alive and well and living in another state with an entirely different family?

Or, perhaps, after innocently taking a DNA test for fun, you discovered your dad was not actually your biological father?

Maybe you actually found our that you have over a dozen half-siblings because your dad turned out to be a sperm donor (something he NEVER told anyone about!)?

So, tell us, do you have a DNA or 23andMe "horror story" you want to share? Tell us in the comments below or use this totally anonymous form here, and your story may be featured in a future BuzzFeed Community post or video!
