What will you do when I feel frustrated?

I felt frustrated in these days because I lost my goal and I do not have enough faith to prepare study abroad. It bothers my so many times. I forgot the ways I used to overcome this blue mood.

"Is this really hard for me? In a life-long scale, this is only one bottleneck of it! This is nothing only if you can not insist on it. Do not say impossible. Try it, and leave something after hard working. Work as much as I think."

"If tomorrow is the end of the world, should I still be blue?"

"Hay! What do I have? Good friends and family. Cherish!"
