I need a sign from God?

Im in a total lost in life. My townhouse foreclosed at the end of 08.All my big furnitue was taken away when they cleaned out my place. I couldn't afford to put them in storage..my car just broke down and now im catching rides to a job that drains me. I try and talk to God but I feel like he can't hear me. Im really trying to make a effort to change my life around. Im thankful that im single with no children so I only have to worry about myself. But im extremely lonely. I went on an interview yesterday for a position that i've been wanting for a while. I asked God if I did well and if I will get the call for a second interview. As soon as the question left my lips i was overwhelmed with a yes. The only problem is the yes was put in my mind sounded like my own voice. Could that have been God? was he telling me that I will get the job? I need a sign from God. How do I ask him. Im completely lost
