Help! Need some advice

Call the police and have them do a welfare check on her, even if anonymous.

Someone talking about taking their own life at any age needs attention.

I think it a good sign that she told you why she needed a ride to the beach. To me, buy I am far from knowledgeable on the subject, she would only tell you that she was going to kill herself because she wanted help. But she needs professional help. Call the police.
