I know couples who go through the same as you. Never a shame to ask for help if you need it, especially when there are kids involved. My uncle and his wife have two girls and they are having a hard time as well. My uncle works just as hard full-time and his job was fine when he was younger but he has passed 55 now so his health is letting him down. He works outside a lot, building construction and he has to travel so much. From the 14 hours he is out there for his job, he gets paid 8.
I'm worried about him because he's got long problems and diabetes now. His wife has a heart disease but is also cleaning houses now to provide for their girls and their education. They don't talk about their financial problems but I wish they would. I know from a niece that my uncle's wife is on anti depression medications... I also know that people would be willing to help them especially knowing they have helped out others so much in the passed. But they don't ask for help therefore I'm only glad that you do. It must be hard enough as it is. Never mind those people who send you ugly messages. Not every one is like that. I am a single mother but I don't think that way. Who is that person who sent you that rude message to judge your situation. I wish you and your family all the luck in the world and I hope everything will turn out for the best...
