Content warning for mention of abuse and narcissism .

For context, my mom was married to my biological father for 16-17 years, in which during that time he was abusive, not to mention he’s a narcissist among other things. Unfortunately, one of my brothers (second eldest )now exhibits that behavior . She has a lot of trauma from their marriage that still effects her, and I personally as well have been harassed at work by my fathers family. I’ve always been open with my mom about them contacting me, as I’d hate for her to hear it from someone other than me. However, each time I tell her one of two things happens. She’s clearly scared and worried for my safety, on the other occasion she breaks down into tears and isn’t like herself for several days. I don’t know if there’s anything personally I can do to help her at all. My mom is also disabled due to a work accident as a nurse , so she is not currently working and does not have much to occupy her time. Unfortunately, we still live in the area of my fathers family so people know her by affiliation, and I think that keeps her from having fun and going out. One reason she never dated anyone after their marriage is she was scared and worried that the man she would date would harm me or my brothers, but also her. I’m sure you can assume in what way. Is there anything I can do? Anything I can suggest?
