Did My Sister give birth to me?

Your not alone. My oldest sister is 16 years older than me. We are the onlt 2 family members living in Canada. i hav e a brother 15 y older, a sister 14 y older, and another sister 9 years older. Due to certian events i now live with my "sister". A few years ago my brother showed me our family tree, and he kept on one part....over and over again....i wa confused about what he wa implying, and then he said "it wasn't " like basically he was saying "it WAS " and then he kept mumbling to me ask your grandmother... but he'd say it under his breath. i quickly went through older photos and my sister is the only one holding me, no photos of my mom pregnant. Ok, sorry to babble about me, but yes i think u have a reason to ask questions. unfortunately it sounds like u aren't gonna get honest answers from yur family.
