What should i do my dad is gonna kill me?
I would concentrate on what your doctor tells you and have him either give you a strict plan to follow or recommend a dietician to do so. The plan should include meal and exercise and should be very detailed. If you follow the plan to the letter your body should respond. If it doesn’t then your doctor needs to find out why. If you are being honest and following the plan your dad can scream at you until he pukes but it’s not going to help.
