how do deal with this?

my problems are small but they are still eating me up inside, my mom is getting married to a bad man, his name is Tyler and he has been living with my mom for years making my and my family's life bad, so im moving to my dads but my dad lives in a rich area so I'm going from bottom-class to upper-class in as little as a month and I'm scared. I'm going to be going to a school where they judge people based on money and power. I kinda feel like I'm in one of those bad flicks.
