I understand what you're going through. I have 2 sisters in college...one is a sophmore and she has made some mistakes she regreted-she joined a fig that kept her from changing majors. my other sister is about to graduate. I dont know how she feels but she didnt make it to pre-med. She is not really sure whether she can find a job. I'm about to go to college in August, and Im not quite sure what I really want to do. I have never faced any thing that could so profoundly change my life. I will be praying for you. May God show u favor and direct you in the right path. I know that God will give you something good in your life.
matt 7:9
"Which of you, if his son asks for bread, will give him a stone? Or if he asks for a fish, will give him a snake? If you then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give GOOD gifts to those who ask him!!!!!!!

May you find peace and comfort in Jesus and guidance from God.
