What else to do?

.So what now that my PMR is over but i feel uneasy of myself on how i did it.Now its almost holiday and i feel to myself i should carry more responsibility and take up a job.I have ask many friends to help me find one,but im afraid that i will not succeed in my interviews.This merely shows that i have no confident in myself or whoever.I think nothing is real and that all is fake.Does this make me too superficial and ignorent?
