I dont have your problem as of now but my fellow classmates have also received harsh words like you.There terror teacher always says harsh things that it will come to there mind that they will stop this course. But my only advice to you is that dont make decisions w/o first asking God's wisdom. You must pray and ask for the holy spirit for help especially in your work. Trust HIM(Jesus). I've been into his comfort and help.. GOD BLESS YOU AND YOUR FAMILY AND ALSO TO YOUR JOB..... :)
