<human>: I was called today for an interview for a job with the federal government (TSA) in San Diego, where I used to live. I applied to this job over 18 months ago and since then my S.O. got a great job (1 year in) and put down roots in Los Angeles, which is also my home town (family here, etc). Her current job makes more than twice as much as this position would and there's no way she would/could/should leave it. 

When I applied for this position, I also applied for two locations in our current city. I have been unemployed (or soul-crushingly underemployed on and off) for the past 20 months since graduating college and my SO has been financially supporting us. A position with the TSA would be a stepping stone into my field and obviously the job hunt has not been going well in Los Angeles. This is the first *anything* related call I've gotten in months. How do I express to the interviewer that I'm honestly desperately eager to work in my field but it would be an emotional and financial hardship to do so from San Diego? How can I ask him to "apply" my interview to locations closer to home? Does anyone have experience with different locations for a government positions like this? Would it be easier/more feasible to transfer after toughing it out "in the system" for a couple months?

Can you give me a shortened version of the text?
<bot>: SO makes bank in Los Angeles, TSA interview in San Diego. How do I tell the interviewer I really want a position in Los Angeles, not San Diego (applied to both locations over a year ago)?
