feelin like a fish out of water

I had been working as a lpn for only the first 20 months at a ltc as only a med nurse. The way the facility was ran was i had only been giving meds no tx no documentation(nursing notes) no nothing but give meds main reason for leaving obvious! I have recently left and took on a position at an adult day service program as nurse case manager.The paperwork is very overwhelming and on week two i am no longer shadowing any1! The job originaly posted for an rn(Bsn) so i dont know if this may be all over my head. Any feedback will be appreciated.Shakin in my boots.
