When did you qualify and what have you applied for?
Have you got an exemplary attendance record from during your training?
Are there any issues from during your training that may hinder your employment?
Sorry to ask but obviously these things would have a baring on you gaining work as a nurse.
Assuming that the above is ok, then i would say, troll the local NHS website DAILY. Jobs come up all the time. Apply for anything and everything. Look in your local PCT as well because the NHS is moving towards 'elderly care at home' 'community hospitals' and 'intermediate care'.
Also, check with someone that your application forms are completed satisfactorarily and reallyt 'sell' you..
Have you born in mind also, that places like Marks & Spencers and British Airways are always looking out for nurses to employ?
Good luck.
