Neither extension nor switching fits my situation

Hi, I am a doctor. I handed in my resignation last month. I have now found another job with a new sponsor. Previously I was working in acute medical unit now I am going to work in A&E.
My situation fits neither extension of tier 2 nor switching in to tier 2 . I HAVE RESİGNED, I AM NOT GETTING ANY SALARY, I AM NOT WORKING ANYWHERE NOW.
Have a look please:

ELIGIBILITY FOR EXTENSION
You must have current permission to enter or stay on a Tier 2 (General) visa.

You must also meet the following conditions:

you have the same job as when you were issued your previous permission to enter or stay in the UK
you’re still working for the employer who assigned your certificate of sponsorship
you’re still earning an ‘appropriate salary’ - read the guidance if you’re not su

ELIGIBILITY FOR SWITCHING
You must already be in the UK under any of the following visas or schemes:

Tier 1 visa
Tier 2 (Sportsperson) visa
Tier 2 (Minister of religion) visa
Tier 2 (Intra company Transfer) visa under the Immigration Rules in place before 6 April 2010 and you’re applying to change sponsor
Tier 4 visa - if you have an eligible qualification, will complete your course in 3 months, or you’ve done at least 12 months of a PhD
Start-up visa
Innovator visa
You can also switch to a Tier 2 (General) visa if you’re:

a dependent partner of someone with a Tier 4 visa
a representative of an overseas business
You must leave the UK and make your Tier 2 (General) application from abroad if you’re not in any of these categories

ADVISE PLEASE

I think I have found a question to which nobody has an answer.
