Found my birth certificate in the attic. It says my stepsister’s my mom—not my stepmom. Confronted them. Truth came out: she had me at 16, and they hid it. My whole life’s a lie. I’m furious, confused, and talking to her feels wrong. Anyone else survive a family secret this twisted? Help. TL;DR: Stepsister’s my real mom. Family lied for 23 years. I’m lost. #StepMomStruggles #StepmomLife #MomAndSon
