What do I do about my situation? is this abusive?

My brother is 22 years old, and he lives with me and our grandma and step- grandfather. He thinks it’s ok to punish me by hitting/ beating me and when he hits, he hits really hard enough to make a bruise. He bosses everyone around even our grandparents and if I don’t get something done in time I have to suffer consequences for it. He acts like he’s my father but he’s not, he has no sympathy he doesn’t feel anything for anyone. He also forces me to go places I don’t want to go and he gives me choices and time limits all the time. LISTEN TO THIS!!! He wants TO BECOME a THERAPIST FOR KIDS. 🙄
