You should never gamble or even trade if you've lost a job and got bills to pay. Its actually worse to gamble when your life depends on it rather then when it was just for fun.

When you gamble for fun, you dont have a goal of making a profit as a result. And you instead take it easy and relax and you might win. When you are gambling because you got bills, you need to win. And you basically go on tilt and start to make risky and bad decisions and eventually you will go broke.

This is similar to a trader who lost a trade, and then he reversed the trade and lost again and he reversed it again and lost more money. You need to know when to call it quit. And especially never after having no income.
