I’m not sure why you brought up the things you did. Your son in college has nothing to do with your present situation. Your dad passing shouldn’t mean anything in your success and survival. Your child at home is your singular issue. 4 years unemployed is impossible unless you’re living on an island. You worked your entire life? That’s like 20 years or so only, you quite possibly have another 40+ years left. You’re the one who is going to have to decide that the excuses are over and you need to either apply to jobs or start a business. Or enjoy the time with your child at home while on public assistance. But stay sharp and be ready! YOU ARE AN AMAZING WOMAN WHO IS CAPABLE OF ANYTHING YOU PUT YOUR MIND TO!
Mechanical Turk: Amazon's Mechanical Turk is a resource for doing human-intelligence tasks, or as the site commonly refers to them, HITs. You get paid a very small fee for any given HIT and you'll need a good deal of volume to make a substantial amount of money. But it is a resource you can use in your spare time to generate a small income online.
Before I talk about some of the methods for making money online, I wanted to address the role of pain versus pleasure. Every decision that we make in life is weighed on a pain-versus-pleasure scale. We will always do more to avoid pain than we will to gain pleasure, plain and simple. However, this is also what holds us back from succeeding in any endeavor.
