I feel for what you're going through and please know in the end it will make you stronger.
For now, resist the worry, beat back those negative thoughts, it will only slow your healing.
To help ease your mind, look at it this way:
1-all those new nurses probably wont succeed and of those that do, they won't all stay (they never do - just law of averages/hiring bonuses/found another job/wanna be a professional student,etc)
2-If the manager wanted to release you she would have. Failure to complete orientation is an easy termination, and you hadn't worked long enough for FMLA or any other protected medical leave. Yet the manager is encouraging to take care of yourself, get better and come back. Perhaps there is something special the manager saw in you, or perhaps she has received a similar break in the past and wants to pay it forward? Just take her at her word.
So, for now: Ask if any forms or documents are needed by HR. Ask for names of equipment you may work with often (pumps/vents/feeding tubes) and look at their images/specs/cautions online. Study when you can - seems a new medication, procedure or supply is released every week - subscribe to a nursing magazine or join a nursing organization, excellent sources of snippets of present day information. KEEP in touch with your nurse manager, keep her apprised of your status, briefly share with her what you've learned, and let her know you are looking forward to returning. This will probably build your loyalty value to her.
Truthfully, it is always a good idea to be mentally prepared to look for work insofar as being realistic about resume weaknesses, making a plan to strengthen it by updating skills, gaining certifications, being aware of market/comparable wages/benefits,etc. So whenever its needed, whether in a month or three years, you can use it confidently.
However, right now, you simply do not need the stress of a job search or fretting over a job you already have. Or the embarrassment of having her find out you're looking! :imbar Trust the position will be there for you :yeah:or else the Lord moved that mistake out of your way.
Nurse yourself, eat well, sleep well, get well.
My two cents, anybody else thinking differently?
