Signing up time

It's time to sign up the PhD examination, but I dare not browse the website for the reason I have no much confidence to try again. From last year to this year, so many things has happened to me, a lot of changes, which changed my body and spirits. The reality makes me down, I nearly can't stand on my feet once again, how can I prepare the examination and concentrate on reading those books? Every day I have to work, and after work, I'm unwilling to do anything. To pass the examination seems a mission impossible. Ahhh, God give me confidence and wisdom, let me fulfill my dream of being a doctor to do what I like and live a more satisfying life. Only in this way can I get out of this depression of my life. God bless me!
