Madiba, you're on social welfare, and you're doing your best. I think you should forthwith cease the 50 Euro repayments. Anyone on social welfare like you have nothing to fear from creditors. In essence they can do nothing for you. No court is currently ordering anyone on social welfare to pay anything out of that towards debts, and your creditors know that. When the new insolvency regime comes in you can try and apply underwhatever scheme will wipe the debts, you're a prime canidate.
You've mentioned emigration, that'a s a great idea. Far better than the struggle you currently have. Have you thought of a location, and how much do you need to make that realistic, perhaps you going ahread without the family. It's better to focus on that, than the dreadful situation you find yourself in.
TommyB, while you manged in your situation to pay back the debt, and that's a really good thing, and in general, always advisable, this man has 2 kids and is struggling. He has no more to give.
