Iam jealous of my best friend, she has it all! cool clothes, a family that is still together?

lives on a nice acreage with a pool, and she is about to go to Cabo on friday with her family, i wish i was her, or had her life, my family is not together, i have my mom and my sister, we are poor, and my dad is not in the picture, we take the city bus and never go on vacations, why is life so unfair :(
