Finals anxiety after everything is finished

This week was my finals week in college and I’ve done so much in the past 5 days. I’ve taken 2 exams, written three papers, and coded a three page website. Not to mention dealing with scheduling classes for next year, applying for an internship and a scholarship for next fall, worrying about going to pick up my house keys for next year. Not to mention that because if corona i don’t even have a bed for next year or anything to move into the house, and have to spend next week trying to find a summer job in a pandemic. I’ve been so anxious that I haven’t slept in over 24 hours, don’t want to drink water or eat, and my chest and stomach physically hurts. Does anyone know how to deal with this?
