It's hard..nobody tell me this before!!!

I am loosing the confidence to complete this. It is hard, extremely hard.....The results are there, but I have trouble to express it effectively, and to draw the conclusion from it. I am loosing my confidence (& almost my mind!) facing this dilemma day in and day out. Di tika dan ketika hati kurang senang dan kurang tenteram, berbagai ingatan lalu....pengorbanan diri ini, adakah dihargai sepenuhnya?
