Think of this like a Paulov conditioning a dog to have an electric shock every time he lights a bulb. At the end the dog avoids the lightbulb at all cost, even when not lighted.
Forcing yourself to do something painful trained your brain and created a trauma with work, as simple as that. Your body wants to help you not letting you work because: 1 work is associated as painful and 2 you can avoid it on the short term, so you avoid it.
A good psychologist can help you easily solve the issue, but probably there are not good ones or are expensive for you on your current situation. A bad one could also damage you btw.
So my advice is for you start learning about psychology yourself and learn how to recover from a traumatic experience using self help info. It is not difficult, basically is facing the traumatic experience but with a good outcome or getting rid of beliefs like "work is painful" that you learned over time. And of course, making work something pleasurable or at least neutral.
Think of this as a curiosity or funny game you play, not like work to do. You could start with "Wake up productive" of Eben Pagan, "The now habit" audiobook and training to remove specific beliefs.
If you are broke you can pirate it. Then pay for it when your life is better.
Forget resolutions and to do list by now. It is making it worse as it is introducing guilt for what you should do, adding more emotional pain.
Start making your life better, independently of your job. Eat well, exercise, enjoy beautiful and cheap places, the best things in life cost nothing...if you are jobless you are lucky and could go to amazing places when people are working, specially in overworked America! Go outside, no inside, and met people.
Start being grateful and enjoying your current situation. It looks crazy but is exactly what you need. Look at it as the opportunity to learn and be a much better person in the future that what you were.
