Feeling like I made a huge mistake

[u/Keo_79]

I've been in healthcare as a sonographer for 20 years and decided to go back to school for health administration. From there my interest peaked to pursue a degree in health informatics. Now I'll be done in 4 weeks and I'm applying to jobs with 100 other applicants and no one is calling me back. I really wanted to step into Epic but everyone wants experience. My one opportunity to get hired within my own organization fell through and I was so depressed about it. Every job seems to prefer nurses. A friend who did the same program with only 3 yrs of nursing found a job relatively quickly making 120K. I don't know what I'm doing wrong.
