I'm going to lead a double life and trick my family
What's the point of leading a double life? What brought this on?
My family doesn't treat me well and it's very upsetting.
Your family should treat you well, but you shouldn't respond to their mistreatment by leading a double life. It's important to be honest with your family so that they know they can trust you. If they find out about your double life, they may come to question everything they know about you.
I don't care I feel like I deserve better and I'm going to show them.
Lying to your won't solve the problems you are experiencing. You need to sit down and talk to your family so your concerns are addressed.
