Help with finances while on medical externship.

Hello, my name is Sara Mayo, I am currently in college to get my Associates of Applied Science and I will be starting my clinicals soon and will be unpaid for 6 months. I had a second job to help with bills during this time, but my boss decided it was unfair for me to work two jobs when the other employees need the hours so they let me go, now I do not know what I am going to do for 6 months with no pay. Any thing will help, but I have children to take care of and can't let them go without or lose our house during this time.
