I sense that my mom loves my older sister way more?

Okay, my sister and I are 8 year apart and we along fine and I love her. But, I truly can't deny that I'm jealous of her in most possible ways. She's smarter, prettier, and nicer. My mom keeps comparing us. And one time, I told her if she can stop comparing me to my sister and she said "You can't even do half the things she does. That's why I do that." & "If I could've aborted you, I would", that one got to me, hard. My mom recently told me to grow and style my hair like my sisters and I asked her "Why? I have my own style" and she replied "You act like you're prettier than her. -_-" and whenever she's with her friends, she always says "You should see my older daughter, she looks just like me :D" and "Heidi's pretty, but not prettier than Kim". Supposedly, she was waaaay fortunate and healthier before she gave birth to me. On her phone she names my sister's contact "Con gai" (My daughter) and labeled me "Heidi". My sister is more of the "As long as my job makes a lot of money, I'm happy" and I'm more of the "If my job is what I love, I'm happy" type. I just wish one day, I can make my mom just as happy and proud as she does, maybe even more.
