"Go work at McDonald's/Walmart/whatever retail for a few weeks/months" is generally not great advice.
Hiring is an investment at all levels and oftentimes restaurants (especially chains/corporations) and retail stores don't want to invest in training someone with higher level skills out of the fear that they'll just leave immediately when something that more closely matches their skills comes along.
Not to say that food/retail jobs can't be found, but in my experience you need to a) not go try at a chain and b) make a more personal connection with the person doing the hiring, not just filling out an application.
If OP is able and has a bike or car (and doesn't mind doing non development work), food delivery through postmates/caviar/whatever has a lower barrier to entry and doesn't require certain models the way ridesharing apps do.
