Need denture repaired but am unemployed in college

I am 30 years old. I have dentures. My top plate got cracked. I was cleaning them trying to install a temporary liner to make them fit better. It slipped from my hand and hit the tile in the bathroom. It cracked. Without using my dentures it is hard to eat. IM stuck with soft foods like pasta, soup, or eggs. Eating any kind of solid food is very difficult. It's hard to sleep. Imagine not being able to close your jaw while trying to sleep. It's uncomfortable. In the morning your jaw hurts because of closing way to far for so long. I am unemployed and trying to get on disability due to medical issues. I am in college to be a substance abuse counselor. I am trying to do better with my life. Things just have been really rough this year. I need help as soon as possible. Once I have enough money I can schedule the appointment but it will still be a week or two after that before I can get in.  A repair is the cheapest option. A new denture would be almost 600. I just need help for now. I would greatly appreciate any and all help that is offered. God bless everyone who takes the time to read this and to donate.
