How do I help?

So recently my mom found out she’s not getting her tax returns because of a student loan she took out over 10 years ago that she forgot about. We are going to Florida on Monday and that was the money we were going to spend. She’s really bummed and even broke down crying in front of me which was really shocking because I’ve never seen her cry before. She asked her dad for a loan because she doesn’t know what to do and we might not even go now. How can I help? I don’t like seeing my mom like this.
