What do you do...

when everything seems to be going wrong? I just don't know what to do anymore. I don't know what's expected of me. My grandpa has cancer, and is unsaved. He doesn't have much longer I don't think. I really want to go home, but I don't think that is an option for me unless something drastic happens. I am not so sure about this whole trusting God thing anymore. Don't get me wrong I trust God completely (I think, well you know it's an everyday struggle) but I am not sure if I should keep going to school when I have no money to pay for it and I am already in over my head. I don't have a paying job and I honestly don't know what He wants me to do anymore.
