Is it normal that my parents are always unhappy with me?

Every time I come home, when I say hi to my parents, they just say hi and sometimes don't even look at me. But it's different when my sister comes home, they get very excited to see her. My dad always tells me that I'm wasting my life away. My mom doesn't, she just gives me the black face or scolds me for doing some things wrong. Like, if I didn't hang the clothes in the way she wanted, she gets angry and screams at me.

They give me a curfew of 12AM and I always stick to it. But even when I come home before that, they always scold me and say that I come home so late all the time.

I know they love my sister because she's very obedient and I'm not goody-two shoes.

But it's really stressful when every day, you come home to see your parents' unhappy faces.

I understand why they use to do that, because I always came home late and I was very rebellious, smoked and drank.

But after one big occasion, my family went through a crisis, and I completely changed. I'm a much better person now and I don't smoke or whatever anymore and I make so much effort to communicate with my parents and try to help with the house chores. In fact, I do almost all of it now. I never did the house chores last time. I'm really trying my best to be a good daughter. But somehow they just keep picking on my flaws and never encouraging me or be a friend.

They got better for awhile but now, they seem to be unhappy all the time with me only.

I deal with depression and they don't even know it. It's so much harder to deal with it when they used to scold me for being locked inside my room, for being distant and cold. They stopped though. Because now, I always try to be happy and cheerful like my sister and I don't lock my door anymore. I hide how I really feel. I deal with a lot of stress outside of this family. I always try my best to make them happy.

It hurts A LOT.

And my sister doesn't even talk to me, she seems very snobby and I feel like she looks down on me. I don't know. We used to be very close.

I would be lying if I said I loved my parents. I think I hate them but I hate myself even more because I just feel so sad.

Is this normal? Do you guys have parents like that and how do you deal with it?
