Oh Twinkie you don't really need this do you. The 3 months is from an official notice of redundancy - your boss mentioning you may not have a job will not count as this.
Your company will not want to let you go - they'd have to pay you off! It's far more likely that they will try to find you something else in the organisation. Of course if that is not a similar job you don't have to accept it. I would speak to your divisions HR person asap to find out what the plans are.
If you are serious about changing career then I would suggest you speak to a career counsellor. They'll charge, but they will go through your likes, skills etc and can find a career that really suits you
