Harsh truth, if you can't get a job in the food or service industry, there is likely a real problem that is also going to make it very difficult to make it as a freelancer. You are basically asking if it is possible to start a business and be successful. Generically, yes, people do that all the time. Can you do it? That is less likely.
That xenophobia is huge red flag that the problem is more you than anything else.
