You ask what you should do in your situation. Some options are to accept that you are gaining weight and make lifestyle changes to get healthier, talk to your father and explain why continuing your education is important to you, or have a respectful discussion with your teacher about ensuring they are alert and engaged during class. You could also consider moving to a quieter neighborhood if the noise is disruptive to your sleep and quality of life. Overall, reflect on the issues, consider different perspectives, and take prudent steps to improve your circumstances. Communication and compromise may help resolve several of the dilemmas.
