[US] Old friend on instagram asked for a favor

I got a message on instagram from a friend I met last summer at one of those week long college courses for high school students. She asked for a favor and I had seen stuff like that before, so I asked if she was hacked. She sent me a photo of herself and said she wasn’t hacked, so I asked her what was up, but then she started asking for money. She later sent a video of herself saying it was really her, so I’m very confused. After the last message she sent, I stopped responding because it seemed like she wasn’t giving up on it. She said she didn’t know who else to ask, but we had only met once for a week a year ago, and hadn’t really been in touch since except for liking each others posts on insta. Is this a scam? Or does she really just need help? Either way I can’t help her as I’ve just graduated high school and don’t have a job as I’m about to move away for college.
