First, don't be depressed.
I have been like you once. Due to bad market condition, I once lost my business, with $700k of debt. Even with all of my assets (houses, cars, jewels, gold) sold I won't be able to pay those, but it's important to stay calm, be logical, and trust that you will be able to rise again.
Secondly, I would advise to find a job. I know that you can find money through IM, but it's difficult to put up great stuffs in just three weeks. My advice is to find job that requires less dedication so that you can also build your own IM empire. Start fixing up your CVs, and sent them out. I know that it's tough to get a job in three weeks, but you have to try. Accept lower salary jobs, you need to keep cash in hand. While waiting for interviews, if you are an IT engineer you also can start finding freelance jobs (just check it in Google, there are various freelance jobs). Some jobs are also available in BHW, in Hire a Freelance section. Try to contact your friends/families, if they got a job opening for you.
Third, while waiting for interview, start creating your IM business. Create a great sales letter, stating that you are expert in SEO, you can help this and this, and send them (in person if necessary) to small business in your area. Small business are more receptive to SEO partners. This is not you looking for a job, this a you starting up a business. You could also contact your families/friends, if they need a help from a SEO experts (but make sure that they pays).
Fourth, while doing all of above, continue to build your own site. Whatever the world throws on us, don't ever quit on your dream.
Fifth, although you are fired finish your job beautifully. Ask for recommendation, finish up works you have given, put up complete documentation, make sure that you depart the company in good terms. Ask you boss for recommendation letter, it's not really powerful, but it may help you.
Good luck, man! Stay strong.
P.S : During times of crises, people are more inclined to throw up their saving for some quick-get-rich scheme, because they are psychologically weaker due to their anxiety. Don't trust someone who may offers you credit without guarantee, treasures in Nigeria, or anything. Use logic, and if the deal is too good for you, it's probably because it's too good for you.
