Happy Birthday and screw your shitty family. Your sister is even worse for allowing it. Figure out what you want to do in the future and figure out how you will need to achieve it without your families help, cause you know you won’t get it. Loans, scholarships, job, car, etc. Don’t let them bring you down or distract you. Be cautious if they change their attitude when they see you doing what you need for you. You let your guard down and they could destroy what you built.
