I don't think this is a good time to quit any job where you get a pay check! But I am a little confused, You said "going for my license in a few weeks for the second time". Are you a RN now, and working as a CNA? In my state you can continue to work as a CNA even tho you have your LPN or RN license if there are no openings for that. As soon as you receive your license, you have to go to HR and apply for a RN position. If you continue to work as a CNA waiting for a opening, you have to be very careful and not go over the duties and scope of the CNA position.
The other thing I thought about, is you saying you are staying in a crappy job. I guess you mean the pay and hard work. But working as a CNA you obtain a lot of good experience for your RN career. You have hands on to care for your patient and learn so much. The CNA has the bedside hands on to care for the patient with caring and compassion. I am sorry to say that as a RN sometimes those traits get pushed to side with everything we have to do. I truly believe that a person who has worked as a CNA or tech has the benefit of taking care of the whole patient will always remember that those "small caring things " you do all the time ( cup of ice, clean bed,ect) will stay with you always.
And as a RN you will have to know and be able to do everything a CNA does and more. And many places do not employ CNA's.
I guess you can see I am "old school"and still think taking care of the patient including bedpan duty gives you the best base for every thing you need to do as a RN. I know, I hardly have time for bedpan duty but when I am called by a caring CNA that observes what is in the bedpan doesn't look right ,or the skin is red or broken, ect ,we are all ahead.
I know in many parts of the country it is hard to get a job as a new Grad, but if you don't have to stay where you are, come South. You are needed "down" here !
