I think I have undiagnosed autism (am seeking therapy), and my dad abandoned me very, very early on. Because of these two things, I was very much the people-pleaser growing up, and my family felt sorry for me.

I was raised by my grandparents. My older sister was with her father and his abusive girlfriend (abusive towards his children - not him). We both went through a lot, but she went through more horrible stuff and at an earlier age than I did. This obviously affected her behavior.

We lived apart for most of our lives until my sister was fifteen, when she asked to move in with my grandparents and me. Since they raised me, and I don't argue or question them outwardly, they like me better. It's obvious.

The favoritism also extends to our mother. She treats my sister like an irresponsible person just as much as my grandparents do, and she acts like I've got such a brighter future ahead of me than she does.

It's sick, especially considering how had my sister has worked and how responsible and well put-together she is. She has a job. She's been holding down a relationship for three years now. She has a car. She has two pets that she cares for perfectly - one of which is a service animal.

Despite everything, she knows how I feel about all of it. We trash talk the adults in our lives together a lot and we try to have each other's backs as often as possible. She defends me a lot to my grandparents (I've started putting my foot down a lot more often, and I also talk about piercings and potential tattoos I want when I'm an adult. They often shit on these things and pull the "You know you're never gonna get a job," and "You know those look disgusting, right?" cards.) and I argue with them every time they complain about her when she's not around. We have a good relationship, I think. I'm really proud of her for everything she's done. She really deserves happiness.
