I’m just hoping someone can help me here, I’m trying to convince my friend to go to a doctor, and she is planning on calling today but who knows if they have time today or tomorrow :/

She was visiting her boyfriend across the country when she started having crazy anxiety to the point she can’t stop crying or shaking. Her parents bought her tickets back home hoping it would help. She’s since been home for over 12 hours (has slept and ate) but is still constantly shaking and crying she’s scared something is wrong with her. She’s never been like this I’m very worried about her she’s my best friend I don’t know what I can do to help??? She’s been feeling this way since December 30th
