I am 15 years old girl and I come from Iceland but I have been living in Norway for 9 months. My mome HATES me, she has allways hated me and I don't know what I did. Everything I do is wrong, she doesn't like my grades (I have been living in norway in 9 months and I get beter grades than my best friend who has been living in norway her whole life), if I walk into the kitchen and she's standig there she goes away, we never do anything as a family because she doesn't like to have me with, I often sit alone in my room on Saturday nights because I am not invited to sit with them and watch a movie. She screams at me for breathing to loud or for eating to loud. She doesn't like if I sit in the livingroom she wants me to sit in my room quiet.
I don't have siblings and my dad works a lot, and he is to afraid of her to say something. And when I tell him that she has a problem he just says that she's my mom and she loves me. I don't think its love to kick you're 7 year old child into a door, or slapping your 11 year old daughter for starting on her periods to soon or tell your teen dughter she is fat in a dress.
When lived in Iceland I went to my grandparents work after school if she was angry at me. But now I have to go home and hear her call me a ***** and say that I am a mistake and I will never get far in life.
She is a vegeterian and has no friends. I have a big group of friends who I love but can't tell them wats going on.
I was a troubel child, and I have a ADD.
I just want my mom to be proud of me and love me, I love her and she is my mom but sometimes I feel like I don't have one.
What can I do??

Just giving birth does not make someone a mother, it makes them a parent. It does not mean they know how to treat others, Also if they are not happy with theirself or perhaps even have their own mental health issues, they can not be there for you. First child abuse, hiting or kicking a child is illegal almost anywhere and needs to be reported. After that, push your dad to do more. And also sorry "invited" to watch TV, your house, you go watch TV If my son waited to be asked to do something, I guess he would be sitting in his room all night to.

This is just a wild guess but it almost sounds like she blames you for her unhappiness. She had to move because of your dad's work, I assume, so there goes her friends, and your dad works a lot, so she's lonely? Maybe she even wishes she could be single again? Parents often take out all their frustrations on their children and children rarely have any insight into their parents as 'people' other than just a mom and a dad.
Someday she might be able to tell you what was going on, and even show love. Maybe not
You are 15, have friends, and they and the world will be your 'family' in many respects in 2 to 3 years, so spend as much time as you can with them and plan your future.
