My sister is mostly asexual but feels bad saying no, so she gives random guys sex when they coerce her. She was crying to me the other day and told me about how she felt used for her body. She said that on multiple occasions guys would start kissing her and then taking off her clothes, and she would just freeze up with anxiety and remained paralyzed until they finished.

She says she is depressed and suicidal. I'm really worried about her. She is very shy and doesn't know how to handle situations under pressure. I'm not sure what I can do to help her. We grew up in a broken family too, so she never really received any guidance from our parents.

How do I help someone in this situation? I am not available to follow her around all the time and protect her.
