I hate my brother loll

Am I the only person who genuinely hates their siblings. Its not like normal bicker I actually don't like my older brother at all. Hes annoying and weird and think he knows everything in the world and it genuinely pisses me off so much like shut up for once. He turns 20 soon and still lives at home. Because he failed all his college classes and spent all my moms money on weed. But if I get a C in science its “unacceptable.” They forgave him so quickly and it makes me so upset. Like how come they don't praise my hard work. And his excuse is “he need help and a therapist for anxiety.” You don't have anxiety you have no idea what its like to be afraid to raise your hand in class and the teacher calls on you anyway because they find it amusingly to watch you struggle to answers as popular bitches snicker and giggle in the background. You have no idea what its like to skip lunch in the bathroom cause the table you usually sit at is full but whatever.
