My Thought and My Mind can be differ sometimes

If people know me and be friend of me because i'm friendly. they are partly wrong and the other part they are right. i'm not that friendly. most of the times, i can tell that i want to be alone... since exam is around the corner. Give me back my peaceful mind so that i won't have any problem in handling myself within this depress state. I WILL SUCCEED IF I DO MY BEST!!!! ChAyaok IKIN!!!!
