I'm a job hopper as well. I'm ashamed to admit it. My first 2 years as a nurse was stable I had two jobs in two years which I stayed at both a year each. Then I started nursing school again and that is when I became a hopper. My school schedule was constantly changing and I could not balance both. I also tried ped HH and hated it. Now that I'm a RN I'm hoping that I'll have more opportunities to find what is the best fit for me.
Many people on AN advised me to seek out another career, however that is not an option. I'm confident in my ability to be a nurse, I just have not found my niche yet. I'm hope it gets better for you. Hang in there. We will both find our place in nursing. Don't give up.
