I've seriously injured myself, but not specifically to avoid work, but I don't work anyway!

Is there any specific concept about your work environment which explains the root of your anxiety? What worries you the most about work?

It would be useful if you could get help with your anxiety.

However to be perfectly honest, work is not for everyone. And it is possible that at this stage in your life, work is not the right thing for you- until you make more progress with your problems.

If you don't feel like you are able to work, it might be good to explain that to your doctor, maybe he can help you get some sort of income if you are not working for a while.
