The adverse condition is that your employment is being terminated, and that your permission to remain in that country rests on having employment. No job, no authority to stay in that country, eligible for waiver of physical presence test. That's the best option given your facts.
The letter from your employer could support the claim, and is attached to form 2555
to support your waiver request. Consider attaching a copy of your employment agreement/contract if it shows you would be there for the 330 days if not for the termination of the agreement. Mention the inability to remain in the country without employment. Not for financial reasons, but that your permission to be there terminates when you lose your job.
A taxpayer must meet all three requirements set forth in section 911(d)(4)(A)-(C) for IRS to consider waiver approval. To consider recent case law, consider Daly v. Commissioner, T.C. Memo. 2013-147 (http://www.ustaxcourt.gov/InOpHistoric/dalymemokerrigan.TCM.WPD.pdf). The Tax court was unmoved by taxpayer's work requirements, and required taxpayer to be resident in one of the IRS listed countries for adverse conditions to receive relief. Having a gig as an engineer in Mexico, for example, does not qualify for waiver relief if the contract can't be completed under your facts.
If I was advising you, I would recommend you find enough out-of-country days to have 330. You did not mention your tax home issues, but the Court in Daly was clear in its test of tax home which the 330 day physical presence waives. Not having banking, a driver's license, your own residence or other factors will work against you if you indeed did not.
I hope this is more specific for you. In the text of Daly, the Court lists several other cases that can support the court and IRS rationale which may be more directly on point with your facts.
