Struggling with my faith and needing peace of mind

I abandoned Jesus for a long time thinking I could live without him. A series of events in my life made me re-think my entire faith. My sleep is not very good and wake up very tired in the morning. I worry about my wife's health who is the bread winner and should anything happen to her, we'll be out in the street.

I have found it very difficult to make some income which I will need when I return back to the USA sometime in 2014. I worry which sometimes leads to depressing thoughts making my life unhappy.
The greatest gift I need is peace of mind and only the J.C has that power to assist me in my difficult time. Let me say, I don't ignore visiting a doctor for my medical problems, as God as provided them with the knowledge to help us. Sorry that I am rambling on but this is how I feel.

I want to put my life back on the right track as one day I will have to face the Lord himself face-to-face. I want to give an honest account of my life to him.

Please pray for me and my wife and family. Thank you
