My story. (trigger warning)

Hi, I am Brittanie, I'm 16 and this is my story. I feel that writing it down and getting it out there will help me realize somethings, so here I go...
It start a few years ago when I first turn 13 something in my mother changed or maybe I realized how she really was, she started to abuse me. It was more mental than physical but it still hurt. The first memory I have of the beginning of this is when she kicked me out of her house and sent me to my dad's because I accidentally broke a Christmas orderment. I remember she just got so mad at me and start yelling. I told her I didn't mean to and that I knew that kind of try wasn't good for heavy orderments, she just blamed me and yelled and took me to my dads. The next was when we got into an arrangement and she kicked me and my sister out of the house. She old us to grab all of the stuff we can and to start walking to my dad's in the rain (whose house is like 5 miles away). 
During this time she was also constantly blaming us (me and my sister) for ruining her life and "almost killing her" when we where in her stomach. She would also constantly call me fat and make fun of me for weighing as much as she does. I then decided to try to lose weight and eventually developed anorexia. 
The next worst time I remember is on my 14th birthday. My mom got really mad at me because I didn't know where my brother stroller was. She shoved me down and started beating me with a wet towel. She yelled at me and blamed me again for almost killing her and she yelled at me for being anorexic and for not knowing where the stroller was. She also told me that I was going to hell because I am such a horrible person.
This continued for a long time until my dad got us full time. She didn't speak to us for months. Then she started forcing us to come over at the beginning of this year. She continued to abuse us.
The worst time I can remember happened this year. My sister just came back from a mental hospital for trying to commit suicide. And my mother thought she was cutting herself in the bathroom again but she wasn't. When she wouldn't show my mother her wrist and other body areas she started threatening to have my step dad holed her down so she could, this made her freak out even more  because that mean he would have to see he be stripped. I started to yell at my mom because of this. She yelled at me to and started blaming me for my sister trying to commit suicide. I finally yelled at her that I don't want her to be my mother anymore and that my step mother was good enough. She left and then she returned angrier. She has my step dad grab me and shove me out of the bathroom. I started to scream and cry because my sister started to too. She called my dad and my mom took the phone and gave it to my step dad. He then dropped it and I went to grab it quickly and he grabbed me by my next and shoved me down and took the phone. It started to cry more. This continued until my grandmother came and took us to her house.
This became common and she kept abusing us like this. She would also kick us out of the house a lot and my dad would always come and pick us up. We stopped coming for a couple months and then we had to go bad over because of court order. My mom started to act different but I have a hard time believing that it is true, no one can change that quickly. However she would still blame me for my sisters depression. But little did they know that I have depression as well.
I mean it is kind of hard not to have depression. I just dealt with it in a different way, which was starving myself and exercising. Also known as anorexia. 
Thing now have became better. My mom hasn't abused us for about 6 months now. But I still have a hard time believing that it is true. I still have anorexia. And it is hard for me to let go because I don't want to let go yet. I'm not ready too. I like being skinny and boney. But I am working on letting it go I just need time.
I was also recently abused my my ex boyfriend, who I did in fact break up with. This story of that went like this my (ex) boyfriend was going to a public in a store because he told me he had to use it. (No one was around, it was in the hallway in front of the bathroom and the place was pretty empty because it was at night. And all day he has been messing around and joking about sex,) but anyway he kinda just kissed me and we made out with is normal but then he started grabbing between my crotch and I told him that hurt. He stopped but then he put his hand down my pants and started rubbing me. I told him again that it hurts and he just kept going and said imagine it feels good. After he said that h took my hand and put it on his dick and started making my hand rub it. I pull my hand back and told him to stop that he was hurting me. And he did. But he kept trying to make me put my hand down his pants. But I wouldn't do it and got him off topic of it. But then he pulled up my shirt and looked at my boobs and started grabbing them, it tried to put my shirt down but he kept pulling it back up, which made me feel uncomfortable. But I ripped it back down. And he still kept on with the hand job until he gave up and got upset with me then went to the bathroom and told me that he was going to go finish what you started. Then we just left the store but he kept trying to convince me to send him nudes and such. I broke up with him the next day and I felt nasty and embarrassed with myself for the next few days. 
I have now decided to move on from that because I am a strong person. I have gone threw being abused before so this is like nothing. 
So that basically is the summary of what has happened to me. It is not all of it because if I did type everything it would have taken days to type. I am strong and I can keep on going on with life and I will be successful one day.
