Ouch,that hurts.
Please correct me if I’m wrong,but I have a strong feeling you were learning EXTRA well,which the Soton hates,so he came along with this tricky test to make you lose your chayshek!
If you can beat this “down” feeling creeping over you,and get yourself AN EVEN MORE RELIABLE AND GESHMAK chavrusa right away–ahh!What a victory,on all counts!
