My sister's boyfriend beat her up and had her send inappropriate photos of herself to him. She's now afraid to be naked in front of her doctor.

I am not sure how to help my sister, and I don't know where else to turn.<br><br>My sister is 22. Her boyfriend is 25.<br><br>They've been dating for about 7 months. I'm 35F, and I want to help her.<br><br>&#x200B;<br><br>My sister says that, about a month ago, her boyfriend started making comments about how she was a "worthless millennial" and was "so lazy for not getting a job." I'm actually a big part of why she doesn/ t have a job. I was in an extremely abusive marriage for 13 years. It ended about 3 years ago, and my kids are now with me. My sister was there for it all, and she helped me get my kids back. She wants to help me, but I want her to have her life and not feel obligated to me.<br><br>&#x200B;<br><br>Anyway, my sister says that, a few weeks ago, her boyfriend started calling her "a waste of time" and "good for nothing." He told her to show him what she was good for. My sister thought this was a weird comment, but she sent him a picture of her in lingerie. He wanted more, and he wanted her to send it from work. She was horrified, but she did it once. He wanted more, and she sent him more. He told her to film herself in the shower at home and send it to him.<br><br>&#x200B;<br><br>My sister was so confused. She says that, at first, she didn't realize that this wasn't normal. She didn't realize she was doing anything wrong.<br><br>&#x200B;<br><br>Then, a few days ago, my sister decided to stand up for herself. She told her boyfriend she wasn't going to send him any more videos, and she broke up with him. He was furious.<br><br>&#x200B;<br><br>He came to her apartment and beat her up. She has a black eye and is in a lot of pain. He broke her phone, so I had to buy her a new one. While he was there, he took her laptop. He came to my house and demanded that I give him money. I told him no. He said that, if I didn't pay him, I wouldn't see my kids again. I said, "Make it happen, or you'll hear from my lawyer."<br><br>&#x200B;<br><br>He left. My sister is scared to call the police because she's scared this will happen again, and she's scared she won't be able to see my kids if their father finds out.<br><br>&#x200B;<br><br>My sister is afraid to be naked in front of her doctor. She is scared she'll never date again, and she's so scared of her ex. She's scared to leave the house. She's afraid to order takeout or anything like that. She thinks he'll track her down if he finds her phone number or address online. She's afraid to go to the bank because he could be there. She's afraid to take my kids anywhere because he could be there.<br><br>&#x200B;<br><br>I don't know what to do. I want her to feel safe. I want her to feel whole again. I want her to enjoy life. I don't know how to make her feel better.<br><br>&#x200B;<br><br>I am so scared for my kids. If their father is willing to do this, what's going to stop him from doing something worse? What if he decides to show those videos of my sister to my kids? I don't know what to do.<br><br>&#x200B;<br><br>I don't know what to do for my sister. I don't know how to make her feel better.<br><br>&#x200B;<br><br>I want her to feel safe.<br><br>&#x200B;<br><br>I'm scared.<br><br>&#x200B;<br><br>I want my kids to be safe.<br><br>&#x200B;<br><br>I don't know what to do.
