I got it for my family as a holiday gift and it was so fun to see what we were vs what we were told we were (and also like the differences -- I'm way more Norweign than my sister in our percentages but she looks more stereotypically Scandinavian).
However, the annoying side is I have two half-sisters I didn't know about. Thankfully, they both pre-date my father's marriage to my mother, but I have a big enough family, and I don't need this. And my father has always been a cheater, so it's just a matter of time before this blows up badly. I wish I had waited until he was dead b/c now I'm being pestered about meeting his kids. Seriously, dude, they are in their 40s and 50s. Biologically they are related to you, but you didn't raise them.
Good luck on the anxiety journey -- I've been through it and I know how hard it is, but when you find the right combo, it will be worth it.
