Second, is there any other way, to come off this, as I the amount is too high, and I can't afforded because I have got two small kids, my wife doesn't work, plus I am paying off my mortgage and the reason for me to go for another job was financially i need more money, too much responsibility.

Can you please give me any advice ?
