So I think I was adopted.?

Theres like no similarities between me and my parents.
Mom: Blonde Hair, Light Skin, Blue Eyes.
Dad: Black Hair, Dark Skin, Brown Eyes.
Me: Red Hair, very light skin, hazel eyes.

And no one in my family looks like me. Also there's like no baby pictures of me especially ones where there holding me I've seen none. Also they don't act like they care ahole lot about me. And when it comes to taking me to the doc. or something like that they act very nervious even though they can afford it. :\
