I am very sorry to hear that. Since they have not provided you with a reason for termination, you would typically be eligible for unemployment benefits since there was not good cause to terminate your job. I would immediately apply for benefits.
It doesn't make sense though that they would not provide you with training like the other nurses unless they were engaging in some sort of discrimination, whether based on race, gender, age, disability, marital status, or a non-protected status.
I would send them a written request for your personnel records. Under state law, you have the right to copy and inspect your records and this may shed some light on why they terminated you so it can be determined whether to file a complaint for discrimination with the state fair employment and housing commission.
