My mom got into a car accident, Why is she crying?

[cinnard]

This happened today she was coming home from work near lunch but didn't make it back in time she told me she said she was driving home thinking I got off work early today I get to eat with my kids and family happily then near the traffic lights she saw with her eyes " green light " and she drove through but it was a red light i'm guessing since she ran into a car herself. She thinks its because she doens't get enough sleep at night she wakes up at 5 in the morning everyday to work and doenst get much sleep. The fault is my moms because what she thought was green light was only red light. She got a ticket and a penalty but now at home she is fine no one got injured she is crying on her bed and I don't know what to say to make her feel better because the insurance is going to get higher and our car is not in a good shape. what can i do to help?
