Is my Career over?

I was hired as a new nurse in a supervisor position but I could not shake the feeling that I needed more experience. I wanted to be a more knowledgeable resource for my staff. So I started school to get my BSN and got a job in a local hospital. Leaving a very good job behind. I loved it, I was learning so much! To my dismay It didn't work out, after only four months 2 co-workers went behind my back to the manager and put complaints against me for talking to much about my personal life and added a few non-truths about med pass and documentation to make me look like I couldn't do the job. The manager never investigated my notes to see if the claims were true, or she would have seen the lies for what they were. I was told I would fail probation or I could choose to resign. I took the option to resign. I was lucky enough to get a job in another local hospital right away, but I was still depressed over what happened at the first hospital. Because I was too depressed about the situation didn't want t have to discuss it in future interviews, I made a huge mistake, I left the first hospital off my job history, so when HR got wind of it I was terminated for omission. Now I have no job, and I'm so frustrated. Is my Career over? Is there any hope for recovery from this?
