All you have to do to avoid any penalty is to go healthcare.gov and sign up for insurance by Monday. Then you will be OK for 2014 (the penalties don't start until next April).
You should do this right away. It is a good thing for you to have insurance, in fact it is better for all of us for you to have insurance (since otherwise we taxpayers have to pay your bill if you need treatment you can't pay for yourself).
I don't understand why anyone would want to go without health insurance.
