Senior Project Deadlock!!!

Deadlock is political term, like political deadlock!
Now i used this term with myself.

I do not know what to answer my friends asking how is my senior project for an Economics degree. Once i told them that i am stuck with it, they did not believe me! It is very hard to convince them. They keep thinking i was one of top students in the class. The more they said that to me, i feel even shameful to myself...What can i do if i really feel stuck with it?
