CA is a community property state. You have information and that information is your W is moving out very soon. File for divorce so you can at least get 50% of what the two of you have (including her retirement account). Yes, that might mean 50% of the credit card debt but it also means 50% of the other stuff. If you only have one vehicle that will need to be addressed and IMO you getting money instead of the car would make the most sense.
Now you know what is going to happen you need to do something. There is no more time to buy and you have all the info you need.
What sort of jobs are you applying for? Are you not qualified to do them? Are your interviewing skills not well polished?
I understand you are looking for a career but how about a job just to have some money for now? You mentioned where in L.A. you live before (I remember but won't say so your privacy is not violated) and I just went to indeed.com and typed in that location. There are TONS of listings for jobs (and no, none are great or glamorous but they are jobs that provide income).
You still have time to hussle and make this a doable situation. Let us help you but you really are going to have to dig deep and rely less on hope and positive thoughts and more on firm and concrete action.
