What should I do about this situation with my parents? I know it's long, but I'm REALLY upset! PLEASE HELP!?

That is horrible. 12:30 isn't that bad especially if you are ping all your cles, keeping up with your ignments and you notice that it's not affecting your health. Honestly I really think that you should talk to a school counselor about these things that have been going on at home. It's not healthy that your parents are constantly putting you down. Please go talk to someone. It's the only way things are going to get better.
