I empathise with you, but sadly you are in a screwed up state where not much can be done except to try continuosly. 39 years old, unemployed for 2 years, failed business, it's gona be tough convincing any employer. Wose come to worse go for the low level jobs like security guard, administrator, storekeeper etc.

That's why I always tell people NEVER to quit your job without another in hand. Quite frankly with 4 mouths to feed and near the danger zone of 40 years old, I'm surprised you actually chose to venture out.

I guess that's life, you took a gamble and the cards didn't turn our right for you.
