I see that you live in the Los Angeles area. I lived in the greater Los Angeles area for 22 years and attended LVN school in the San Fernando Valley in 2004 and 2005.
My point is that you have numerous employment options since you are in the second largest metropolitan area in the nation. With your valuable 14 months of experience in skilled nursing, you can get a job in home health, hospice, long term care, med-surg hospital nursing, outpatient clinics, or virtually anywhere. There's no valid reason to stick around at a job that is burning you out when other workplaces will value your skills and contributions.
Good luck to you! I hope everything works out for the best!
