The Big Bang Theory 14th anniversary 2007 2021 thank you for the memories shirt

So this is actually my story of when I was a kid. I had an imaginary friend named Derek who was a carbon copy of The Big Bang Theory 14th anniversary 2007 2021 thank you for the memories shirt. We were completely identical. I played with Derek for years, longer than what normal kids do. But he would always look at my mom and older sister with a sense of sadness. Eventually he went away. 23 years later im digging through my moms safe to grab some paperwork she’s kept for me and I see a stillborn death certificate for a boy named Derek who shared my birthday. It was only then I found out I was actually a twin and my twin, Derek, died during birth. Creepy right?
