Out of ideas.... Help???

Hi everyone!! Thank you so much for reading (this is kinda lengthy)!

I'm finishing up my pre-req's and will be taking the NET exam this summer. I would really like to get my foot in the door of the medical world. I have applied to become a NA at multiple hospitals a number of times and have been rejected everytime. I think this is because I have no prior medical backgroud (that I can understand). So I have been looking very hard at becoming an STNA and found a couple programs that seem great. I found a NH that offers a two week course and then a possible position afterwards... problem is I need to give my current job no less than two weeks notice, and the NH is only giving me a weeks notice as to when the next course is offered. I then found that Meridia (yay!) is offering a three week course to become an STNA. You fill out an application for an actual position and then they train you... problem with this one... they wont hire me!

I understand that a hospital can not just hire anyone off the streets and give them a job taking care of people's lives. But I dont know how else to get involved! I will be on a waiting list for 2 years before I get into the Nursing program at school, and I'm afraid that when I get into the actual program I'm going to realize that I dont like nursing!! I could pay for classes to become a MA, but I'm on my own and am really trying to keep the cost down.

I was hoping someone would be able to give me an better idea or maybe a dose of reality! Thank you so much for taking the time to read this!!!

God Bless,
Patience
