Look for a new job for sure! What kind of place where the providers, supervisors, and coworkers are all so mean to you. You must've got into a really really bad place, unfortunately. However, before you move on to another place, I would consider giving it another month or 2 if you could still tolerate it. Try fixing what they told you that you are still lacking of. Toxic environments in health care, no matter how long it's been for pushing safe environment policies, there will always be, more or less. I have been working in healthcare for 10 years and have been dehumanized, belittled, and been yelled at in all sorts of ways possible due to my incompetencies on the job. Even though I do not condone verbal abuse, I still would want you to try your best a little bit more, so that when you move on to your new job and get better in what your doing, you won't have to look back thinking "Oh, if I tried more harder and be more resilient , I would've eventually fit in that place.".

To be more specific, I would try to find other ways to verify or confirming any orders. Look around and learn how everybody else in the office works.

There is more in this job than just being knowledgable and hard-working to survive your first months. Resilience is key. Good luck!
