OMG this is exactly my situation. I signed up for all nurses to post a question about this very same subject. Just when you think you're the only one struggling. Anyways, everyones advice here is so helpful and I believe them to be true. However, I think that as long as you are willing and you have the drive to succeed then eventually you can be the resource that you are desiring to be in the ICU. IMO it just may not happen in the context of ~6 to however many weeks long your training was, (sounded short). That being said, it may be disrespectful to piggy-back my experience on your question so I think I may have to post my own.
