Where you truly are paranoid Brian is not reflected in your post. I am guessing it is how you feel about the future. You believe that if you lose your job, your life will get worse, and that is usually not the case. Every time I have been let go from a job it hurt initially but in the long run, it was always for the better. I suspect that you lack faith that if a door is closed, God won't open up a window, and He almost always does.
ESTPs are the types of laid back doers and producers employers love to hire. It is easy for me to see that with you because I am on the outside looking in, but I have felt many times what I suspect you are feeling now.
In today's society because of food stamps, Medicaid, and unemployment, you can exist without having a job. Sadly, some unemployed people are better off that those who work for a living.
A penniless ISFP made quite an impression on me. She stunningly went from job to job complaining about all of them until she found one she loved. The Fs I know will not work a job they do not like. For them, happiness trumps money.
We probably need to learn from the Fs on this because I know when I worked jobs that I didn't like, I spent more than I made. Suze Orman, the personal finance guru, taught me this. One of the most common causes of excessive spending is low self esteem and with us ESTPs sadly we don't even know when we are suffering from low self-esteem.
