My 30-year-old younger brother treats my whole family like garbage, and today he finally cursed me to my face

 I have one “blood-related” younger brother — my only sibling. But he acts like he’s the “boss” of the whole house. His personality is a collection of the worst traits from both sides of the family. I don’t know much about my father’s side because I grew up with my mother’s side, but my brother is exactly like them: extremely lazy like my uncles — sleep → eat → play on the computer → sleep, repeating endlessly. And on top of that, he’s a “lives-in-the-mosquito-net” type of person. He barely ever leaves his bed and his mosquito net except to go to the toilet or use the PC… he even eats inside the net most of the time.

Besides that, he’s no different from my grandmother: stubborn, disrespectful, and completely lacking any sense of family. There are 4 of us at home — my dad, my mom, me, and him — and he has already cursed at all three of us. If the “boss” is sleeping and the family accidentally makes noise, he’ll smash things and yell. But when we are sleeping, he doesn’t care at all; he makes noise however he wants.

Just yesterday (Nov 18, 2025), he was livestreaming a game, and he needed the toilet but someone was using it. When it became available, my dad gently informed him: “The toilet is free now.” But he raised his voice: “I’m livestreaming, don’t talk….”

Then today (Nov 18, 2025), I walked past while he was livestreaming and he cursed at me again. I only replied, “I just spoke softly, it wasn’t loud.” And then he went full disrespectful, right in front of my mom — cursing me nonstop with “mày-tao” like talking to an animal. (I never speak to siblings that way because my mom told us since childhood she hates siblings addressing each other like that.)

I said to my mom, “See? Hào (my brother) doesn’t even see me as his older brother,” and he replied, “Your mother! You don’t see me as your younger brother anyway.”

My mom said, “What’s wrong with you today, Hào?” and he yelled, “That fucking idiot suddenly gets horny and starts shit.” Meanwhile I was still speaking gently, calling him “Hào,” calling myself “Anh.” His temperament… it’s exactly like my grandmother’s — stubborn to the extreme, no sense of family, curses others but expects everyone to stay silent.

And this is a shared room between two brothers, not his private room. Livestreaming in a shared environment means background noise is normal. In these situations, most people would accept it or just use push-to-talk like I do when I livestream. But no — he’s the “boss.” If he wants peace, then everyone must obey. Why doesn’t he get a job, earn money, and buy his own house to livestream in peace? His livestreams don’t even earn money. If he did make money, I can’t imagine how much he would terrorize the whole family.

Honestly, since I was little, I’ve always cared so much about siblings, including my cousins. On my mother’s side, I’m the oldest among all the kids. When I went to school, I rarely used my own money for myself; I saved it, and sometimes used it to buy things for my brother. I remember in secondary school, we studied in the same school. He had money, so he bought snacks, but one day he was thirsty after school and I gave him my money to buy a drink. Later when I reminded him about it, he said, “Who told you to give me money?” That hurt a lot.

Today he completely flipped and cursed me. I know my mom is sad, but I’m even more heartbroken. I can’t even describe the feeling — just this hot burning in my chest. It makes me feel like my life is miserable.

Recently the family has been struggling financially. Everyone is working so hard to make money. Many nights I can’t sleep because I keep thinking, “What should I do?” My brother, though — he earns nothing. He’s 30 years old but lives like a completely spoiled, useless person.

Eat, play, drink, sleep — all from the money my parents worked so hard to earn. I’m not that good either — I make a little money, but not much. And that alone makes me worry, feeling guilty that I can’t help my parents more. Meanwhile my brother… doesn’t bring home a single cent, yet treats the family like garbage.

He doesn’t realize that when he came into this world, he was just a tiny piece of flesh. It took the effort of my parents for him to become this 80kg adult. Feeding him from a few kilograms to 80kg — how much effort did my parents put in? Now he’s tall and handsome on the outside, but inside he’s just a useless, lazy, disrespectful person (even though my parents gave him a proper education). A liar too — talks big but does nothing. Everything he eats, drinks, and sleeps on until now is paid by my parents (and a little by me). He hasn’t contributed anything.

Usually my mom brings him his food directly into the mosquito net. If she forgets chili sauce or something he wants, or does something not exactly how he likes, he complains and nags. My mom made the food — but he still grumbles. The kitchen is only a few steps away but he refuses to get up and do anything himself. Whenever I do something, I always think carefully so I don’t make my mom tired. But he has no sense of family at all. If something goes against him, he curses everyone.

Just because we kept tolerating him, kept avoiding conflict, kept worrying about making my mom sad — that’s why there is now a monster like him.

Today when he was cursing me, my mom asked:

“If one day I’m gone, what will the two of you do?”

He answered:

“Just grab a machete and kill each other.”

My mind is a mess…
I want to leave, but I don’t know where to go.
And if I commit suicide, that would be stupid — it would only hurt my parents even more and leave them alone with this heartless brother.

I think maybe I’m just writing this out to let my heart breathe after being cursed today.
Sad for my family.
And my brother is still sitting there playing games…

If one day I’m gone, it will be because of him.
