Go to your local food bank, that should help your food situation for now. Once you get some money get a giant bag of white rice and a cheap rice cooker. Eat the rice plus any protein and veggies you can get to make low cost meals as you financially recover. In terms of tech skills that can be developed Google offers several free certifications in Google analytics, Google ads, etc. Get a few of those and practice (should only take a few days) and try to get an entry level digital marketing, SEM, or PPC role. Once you get the role keep practicing and expanding your certifications to increase stability.
