I'm sorry that's your family dynamics. That's really hard and hurtful. My cousin is the favorite grand daughter in our family - there are only two grand daughters. So I kind of get how your feel. I don't know what to tell you. It stinks sometimes. I wil say that now that we are both adults, my cousin is the one that gets to deal with grandma all the time. She's now paying for being the favorite. Hang in there.
