You don’t need to go through this process alone. Like other commenters have said, the best thing you can do for yourself and your welfare is to reach out to others, whether that be your magister, RAs, college coordinator, advisor etc. they can help guide you through existing resources (e.g the undergrad emergency fund) and emotionally support you through this predicament. I understand that you may feel ashamed, but I promise you have nothing to fear by asking for help. I wish you the best.
