My family need to be less rude

Everytime. I say something about highschool someone got a smart comment. Like “” yea your a fool for dropping out”””. Main fact I didnt drop out I fail my this year ( freshman year). Now they think am dropping out. That bigger fact is that all them fool’s drop out. I going to pass high school to laugh in there faces. It would be nice to have some support.counting the fact that I dont got a godo relationship with a lot of my family members. the best one I got is my brother and grandma.I would had a good one with my dad to. But he dead. So they probably a reason they think ill drop out. Just like when I become 16. Am going to work at kroger. Like next year. I gotta go to t.a.p ( a non-normal high school for kids who miss to many days of school). After I pass that I can go back to normal high school. They think am dumb. ( took a iq test got a 118). My family is just a bunch of rude hood rats. Just cause I mess up one time. They act like people cant change. Yea I made some bad choices but who havnt? Am sure everyone in funadvice made some really bad choices. They probably paying for it right now. I already pay for my mistake. My family making it a bit harder to pass t.a.p. That my main problem. The work is hard and stuff. We dont get homework. And the teacher act like she cant help nobody. So it would be nice to get some support. They alway call me lazy and stuff. But before I got sent to t.a.p. I got up at 4:45am for school and left at 5:55am. My brother sister. Was mostly late for school. Who feel like my family can help me out more. And be less rude?
