Your Best Friend Has Confided in You That She Just

Your best friend has confided in you that she just found out her sister was the victim of sexual abuse from her boyfriend of a year. Your friend feels guilty that she didn't recognize the signs beforehand so that she could help her sister get out of the relationship sooner, and she blames herself. What advice can you give your friend?

A) Your friend is right to feel guilty, but there's nothing she can do about it now.
B) Your friend should talk to a professional.
C) It's important that your friend's sister can heal without the extra distress of her family members feeling sorry for her or guilty that they didn't act sooner, so she shouldn't talk to her sister about how she is feeling.
D) It's important that your friend's sister can get emotional support from your friend, so they should be open about the guilt your friend is feeling.
