What a wonderful question.
Firstly, I am very sorry to hear about you losing your job. I know this feeling myself.
Okay, now, how to pick a career that you love and get paid for. This actually all depends on you.
'Do you like one thing more than another' should be your first step. Take a piece (or a two) of paper and write down what you like doing. I know that some of us who have spent a lot of time under a thumb (such as being suppressed by corporations, people, etc..) do not exactly know what it is that they like doing. If this is the case for you, as it was for me, experiment. Try painting, drawing, writing. Play with animals. Read a book on any subject. Try your hand at all sorts of things. Odds are, you will love one or many hobbies.
Personally, I had to write down two pages. When I was done, I wrote down beside it what jobs fall under that particular category. Then, I would try to condense them. For example, if you had Art/Drawing on one line and Playing With Children on another, I would write Art Teacher/Pre-School Instructor between the two.
My list had animals and writing, art and children. My job is to take care of dogs while running an animal rescue. I let neighborhood kids come volunteer (to build their character) and I love it. As far as the writing goes, I make money off of my published novels and haunt HubPages in my spare time.
If, say, you decide that your choices of likes can never be a career, I think you should probably keep them as hobbies and get a small part-time job in an area you like to keep the bills at bay. This could be a 20 hour a week thing, and devote the rest of your time to your hobby. You only live once, so enjoy it.
That being said, nothing is impossible. You can do big things, but first I would start with writing a little list.
