I am so sorry to hear of your plight. My wife and I have been in your exact position in the past...and although it is very difficult to see at the time, things will work out for you in the long-run.
I can attest that during these tough times, it is extremely difficult to try and be positive; and your emotions become all messed up.
What helped my wife and I during these times was knowing that our relationship has grown stronger by going through tough times together.
Unfortunately there is a lot of unfairness out in the world today...which understandably can turn a persons heart very hard (those who are desperately in need get very little help while those who have no desire to be productive nor help themselves get the majority of the help). This is not cynical nor mean, but just an unfortunate fact in todays world.
Try not to let the unfairness we are surrounded by turn you bitter; but use it as a chance to strengthen your relationship with God.
Here are a few verses for you that I hope will give you some assurance and inner-peace:
And we know that all things work together for good to them that love God...
O LORD, be gracious unto us; we have waited for thee: be thou their arm every morning, our salvation also in the time of trouble.
God is our refuge and strength, a very present help in trouble.
2 Therefore will not we fear, though the earth be removed, and though the mountains be carried into the midsta of the sea;
3 Though the waters thereof roar and be troubled, though the mountains shake with the swelling thereof.
Good luck to you and your family, and many of us here will pray for you.
