Feeling Overwhelmed by My Family Situation

Assalamu alaikum, I really need to get this off my chest. I grew up in a South Asian Muslim home, but my parents aren’t practicing. For the past two years, Alhamdulillah, I’ve been trying my best to learn and become a better Muslim. I know it’s a big sin to say this, but sometimes I just can’t stand my parents anymore. I love them, and I’m grateful to Allah for all the blessings, but what I truly needed was their support and love. Instead, they kept putting me down, calling me a failure because my grades weren’t perfect. When I wanted to study in another city, they said I’d never make it, threatened to disown me, and didn’t even let me try. I’m only 20, and now they’re pushing me to get married. I told them I want to wait, focus on my studies, and that I actually like a brother who’s also studying. He spoke to his family, and his mother suggested we have a nikah or engagement after he graduates. But my parents are so eager to just marry me off, they don’t even want to meet him. I don’t understand what I did wrong. I’m starting to feel resentment, and it’s making me hate them for how they’ve treated me my whole life. I feel lost-maybe Allah is angry with me for these feelings, and that’s why nothing is going right. I feel so alone, like there’s no one to help me.
