Is it normal to have a overly strict mother?

Ok. So I'm 20 years old and I live with my parents, and my 2 sibiling who are younger than me. I have a crazy controlling mother who will do anything to see me suffer, she hates my friends, she doesn't like me going out, and if I do it would be to the mall for 2 hours and I have to come home straight after that or she'll complain for a whole week about me going out, mind you I only went out for 2 hours. I'm not allowed to go to parties or clubbing or even friends birthday parties because it finishes late, I remember one time it was my best friends birthday who I consider a sister, anyways we all went out to dinner and she wanted to go out after I already told my mum that I was coming home at 12, it wasn't even 11 and she started blowing up my phone asking where I was and If I didn't get home by 11.30 she was gonna beat me up, and once I arrived home she told me never to call the girl again even though that's her friends daughter, I just sat there and didn't say anything because I'm that's scared of her. I do everything right I look after my siblings while she goes out and parties every couple of weeks, I clean the house, I cook, I make sure that my sibiling a are find, I pay bills, I pay for everything that I need, I work but my mum takes the money and pays it towards the house thug she wanted to buy. But still she verbally abuses me about everything I do, I'm never good enough in her eyes, to the point where she has chosen my career path what I have to study at university, I tried to convince her that I don't wanna study what she wanted me to, and she said it's either I leave the house or study what she wanted me to. Which lead to my depression and she found out that I have depression, and you would think as a mother you would want to comfort your child, but instead she told me, if you have depression I don't want you in my house and people asking me or blaming me for you nonsense behavior. I can't take it anymore I feel trapped I don't, talk to a lot of people or even have friend because I cant hang out with them because I'm always baby sitting my siblings, I've come to a point in my life where I'm so weak that if anybody says something mean to me or even in a joking matter I break down in tears, I'm so emotionally scarred that I no longer know how to geneinally laugh or have a fun time. My sister is 13 and she is the complete opposite of me, she takes no shits from my mum, she talks back to her and always stands up for herself and my mum never says anything yo her, but if I try to stand up for myself I get verbally abused. I don't know what to do anymore.
