I do I tell her. I feel ashame.my wife already says I dont earn enough for the family and ask me to take on second income

Dont feel ashamed and dont underestimate your capabilities. I admire the fact that despite the difficulties you are facing, you have not given up. That is very important. Our character and attitude. If both our character and attitude are good, one day slowly but surely you will see the returns. Be patient with your wife, iam sure she is worried and has her fair share of troubles too. End of the day, both of you are still doing your best. We will be here cheering you on!
