Hi guys! OP here :) Well, after a long talk with my parents, turns out I am adopted. It certainly came as a shock to me because my grandma (yup, same one) spoils me to this day. I am 22 years old and I am the only adopted grandchild and am yet my grandma's favorite (I'm not even kidding!). I gave her her first great-grandchild and she loves him more than life itself. Granted, I would have preferred to have found out another way, but it doesn't affect me at all. Thank you for the nice comments!
